Default WANTED: I think a C3 rear end will fit in my C2

I have a 1964 coupe with 4.11 gears and I'd like to change out to a 3.23 or 3.36.

I THINK a C3 rear will bolt in to my C2. I'm looking for a rear end unit, gears inside the differential that does NOT beed rebuilt.... not a complete rearend.

I'm in central PA.

Thank you

C3 rears up to 1979 will bolt in. But find out what width spring it has as after 77 or so it went wider. Not too much a big deal as you can swap rear covers, or get the aftermarket one for like $100.

Or consider swap to OD trans? Figure a 0.7 OD ratio will make it your 4.11 a 2.87 rear for nice cruising!!

I've looked at the O/D swap but the pockets aren't deep enough to handle that. That would be my first choice but I'm on a budget and the gear change is my only viable change. Thansk for suggesting and the info on the wider spring

I TOTALLY understand. When I was restoring my '66 I bought a '79 rolling chassis because I needed so many things, especially the 3:55 rear!

Hope project creep does not bite too bad...lol

Thanks for the offer but I am looking for a 3.36......I don't think 4.11 to 3.70 will make the difference I want.

I drove a C2 with a 3.08 and it required clutch slippage to get it going on hills here in PA.

I think 3.36 is my best bet.
