Hi I am new to the forum,

I have a friend with a 68 Rambler American. He is building a killer street monster with a built 258 and T-5 setup. We plan to go racing this year at Pacific and he feels that the Dana 15 will not hold up to side steppin the clutch. I know the V-8 Ramblers had Dana 20s but finding a Rambler in general is quite a feat. My question is, does any of the later Dana 20s out of cars like the Javlin have the same width and perch location for a direct bolt in? What cars and what years can I get a donor Dana 20 out of? He does'nt want to cross pollenate but bottom price will sway him. So maby are there other swaps out there that may work? What have you guys used? please help, racing season is apon the Northwest.
