My grandparents '62 Lark deluxe had the 3.07 rear in it. My father said with the 259, it would run faster in straight high (over 100) than it would in overdrive...
Good luck.Paul Johnson, Wild and Wonderful West Virginia.

"it would run faster in straight high.... than it would in overdrive..."
That's a good thing for a road car, especially for gas mileage. If top gear overall ratio is such that it results in the best top speed then there is typically "too much" reserve power when cruising, so I'm operating in 3 or 4 islands too low on the BSFC curve.

If you can't find the manual, PM me, I have it in PDF format.

Doesn't apply to your switch, but the carriers are different for ratios over 3.90. If you are switching from a 3.31 to a 4.09 for example, you'll need to change the carrier also.Dick Steinkamp

The Dana 44 requires a case spreader, a dial indicator and an appropriate depth micrometer to properly change the gears. I never did a Studebaker Dana 44, but I did the Dana 44 in my Sunbeam Tiger.
It first requires setting the pinion depth. This is done with the tapered roller pressed on the pinion. The race is set into the housing and a measurement taken. It sounds simple, but everything was very tight. I had the race in the freezer and propane heated the carrier. I had the parts in and the measurement taken in 10-15 seconds. Regardless, it was a chore to pound the race back out (large wooden dowel and a 5 pound hammer) without damaging it. You have to do this as many times as it takes (adjusting the shims) to get the pinion depth correct.
The ring gear carrier has the bearing pre-load and back lash set with shims also. Basically you s-p-r-e-a-d the housing .007 of an inch, slide in your best "geusstimated" shims and release the spread and take the measurement. Then you remove the carrier (spreading it again) to adjust the shims keeping the preload correct, and adjusting for the backlash. Again, as many times as it takes.
Between having to beat out the pinion race and holding my breath every time I spread the case (just waiting for the "crack") it was a rather nerve wracking experience. If you don't have the tools, and grasp the process it is well worth having someone else do it for you. Here is an article I did over at the Tigers United site on setting my gears up: http://www.tigersunited.com/techtips...tResto101D.asp
BTW, the case spreader was made with scrap steel, bolts and inverted spring compressors, the ends of which were held in place with an electrical conduit sleeve. The depth mic I inherited from my step-father and the block (with holes) straddling the bearing space I made about 35+ years ago when I thought I was going to be a machinist.

The first poster (62champ) answered it...
