63 Avanti master cylinder.

I've a slight leak where the m/c connects to the power booster. According to the parts catalog there is no gasket between these two surfaces. What would you do? Making a gasket? Using permatex liquid gasket?

This would indicate that the rear seal of the M/C is leaking. The fix is to remove and rebuild/replace the M/C.

If your M/C is the original single circuit type, this would be a good time to consider converting it to a dual type for safety considerations.

What he said!

I agree. This is definitely a case of where safety trumps purism and originality. Go for the dual master cylinder.

It'll soon stop leaking, but the car won't stop at all once the fluid leaks out.

Nostalgic Motors in Michigan might carry a conversion kit (ie, the necessary steel lines). They do offer kits to change from the NLA early-70s master cylinder to a more common m/c.

My Avanti's are early 63's which have a brace on the underside of the hood that a dual master cylinder hits, so I had to go back to the single (original) master. I did however use one from Ed Reynolds that had been sleeved with stainless steel, so that should at least add to the life of the part.

Warren there is a way to adjust a dual MC to fit under the hood of the early Avantis. I believe it involves using some spacers on upper bolts where the power booster mounts to firewall to give the MC a little bit of downward slope. Check out Bob Johnstone's web site.
