Thank you for posting, looks like a great project. Keep us in the loop and I'm particularly interested in the chassis and Hemi install. Welcome, Bob
I have two 341 Desoto Hemi engines. One disassembled but rebuild-able core for mock up and another completely built and ready to go in.
Hothead's trans adapter and flywheel in the box ready to put the 700R4 behind it.
I think all I need is a seat and that is the end of my parts search on this one. Im going to be running 38 tail lights and it took about a year but I finally have all the 1939 headlight parts. Those are pretty hard to come up with.
For those interested, the frame on the 39 is super narrow in the front and I didn't find anything that was even close to the right width. Its 22.5 wide inside the frame rails at axle centerline. Im going slow and cutting and fitting very carefully.

Its got a 4 linked S-10 4x4 disc brake rear-end and I'm doing a Mustang II front end right now. I just started front end this weekend.
I have all the original suspension available for anyone that needs it. That is why I signed up here.
I hate to send it off for scrap, so I figured I would offer it up here to anyone that needs it.
Pick up in Dallas TX.
Its a 57 Desoto Firesweep we just picked up a few weeks ago. The Wife's dream car.
Good luck with both rides. Looks like you and the wife are in for some fun times!

It was the proverbial "barn find" that we found about year and a half ago. It took some doing, but we finally got the one owner car. Clean gas and a new battery and its running like a dream.
The "First Love Project" on RacingStudebakers forum has some great photos and information on narrowing a modern frame for use on a Hawk project. The new frame happens to be from a 2002 Durango, but I think there are some tips here you could use. I am including a link. You want to start on page 18 and follow from there.

I will be bringing the front down a couple more inches at ride height. Hope I have all that done this weekend.
I'm not modifying the frame rail width. Just making the new MM II cross member to fit the old narrow Stude frame. Since the car is considerably lower now, I am having to move the front axle center line back about 3 inches to keep the wheels centered in the wheel wells.
HemiCoupe, who did you source the suspension parts and crossmember from?
And this was the weekend progress, I got all the old cossmember cleaned away and new boxing plates made to patch that area. I have to get all the front sheetmetal lined up so I can center it in the fenderwells and make a new core support bracket that goes from the new crossmember to the bottom of the core support. I hope I can use the old one but I think its going to be too short to reach now. Hopefully I don't have to start from scratch.
I got the whole works on Craigs list Cross member, a-arms, new rack, new spindles, new brakes and all that and a complete air ride management system for 1200 bucks. this is what I started with and what I ended up with.
I decided to take a break from the dirty work and fish all my dash parts out of the molasses bath they have been soaking in for the past 3-4 months.
I have all of the parts including the radio and clock delete plates. Now what to do about the gagues? Has anyone had any luck having these rebuilt for a 12 v system?
You can use the 6 volt gauges along with their corresponding 6 volt senders, by using a voltage regulator on each gauge.

I am considering putting something like this behind the speaker grill in place of the speaker.
(It would go Unseen unless the car is running)
And then giving the stock gauges a quick make-over (new paint, lettering and glass)
The original Oil and Temp seem to have been manual and not electric and the leads were cut off right at the back of the gauge.
Well its finally all welded up and now I can get on to the fun stuff!
Like cramming the 341 Desoto Hemi backed by a GM 700R4 in the engine bay.
Last night I finally put the hotheads transmission adapter to use. If you have never used any of the Hotheads early Hemi stuff its is really amazing quality. Its expensive, but its nice and they are about the only place around that offers anything for these old dinosaur engines.

Using my bare block to cut down on the weight for building the motor mounts.
Last time I hung a 440 mopar / 4 speed on my cheapo hoist for very long the cylinder gave out... and the fully built 341 Hemi weighs more I do believe, and this 700R4 isn't light either.
Thanks for showing us your progress! I always learn something from "build" threads like this.

Thanks! Im going to get the engine / trans between the frame rails tonight. Seems like there is lots of room until the heads go on.
We will see how it goes.

Well its now between the frame rails!
As of now I have not had to cut any floor, firewall or frame, but I am going to start trimming the floor so it can come up a few more inches.
I would like the center of the tail shaft to sit a little higher in the x cross-member and then I can level the front of the motor so the intake is parallel to the frame rails. I was really happy that is as close as it is for a first stab at it. I still have about an inch between the firewall and the back of the passenger side head. I have to get the front clip back on to make sure I have radiator clearance but I think it will be just right.

That FireDome looks great between those rails.
Looks like you're gonna have to figure out the steering around that motor.

Not sure if this will work or not, but I now have the air ride on the front working, at least with a hose from my air compressor!
On to steering now...
Another Busy week.
I got the dash in and now I finally have steering! The Cadillac Tilt / Telescope column seems right at home in this Coupe.
And I got the air ride stops pretty much where they are going to be, At the lowerest point, Im 1.5 inches from the ground at the rear
and 2 inches from the ground in the front and no part of the engine or trans hangs below the frame. This will be my first air ride car and I have heard that they all have pressure issues at some point or another. I wanted to make sure that if/when I loose air pressure I can safely get it off the road and possibly home.
