When you put a 1975 front end under a 1965 f100,Do you keep the 1965 springs or use the newer springs from the 1975 truck you got the I beams out of?
Thanks Russ.

 

Did the 75 have the same engine as your truck? When I did mine I bought new springs, and they wanted to know what engine, trans, and did it have air, so I guess it all is related. Plus how weak are your springs? All this is food for thought. Good luck

 

Keep the 65s unless they are worn out, then try the 75s and see what sits and rides better.

 

I used the 76 donor springs with my conversion. No issues.

Thanks for the reply, I will keep the originals, the truck has a 352
