Hello everyone, I have a 1969 Olds f85 Cutlass without A/C that I am doing a disc brake conversion on. While I’m doing it I’m wanting to put new upper and lower control arms, new springs and shocks. However at this point I am having a hard time finding new springs for it. The car originally had a 250 ci Straight 6cyl in it. About 25 years ago my dad put a 350 Olds in it when I was in the service. He tried to put new V8 springs in it but they wouldn’t fit, so he put the 6 cyl springs back in. Does anyone have any suggestions where I can find new 6cyl front coil springs? I searched and called OPGI and they don’t have them. May have found them on RockAuto but can’t call to verify fitment because they don’t have a customer service number to my knowledge. Any help would be greatly appreciated! Thanks!

 

There is no difference in the suspension arms or other hardware between I6 and V8 cars. The V8 springs fit in the same place as the I6 springs.

 

Regarding vendors. I'm going to toss in my 0.02 for UMI Performance because they produce/manufacture excellent equipment, IMO. I used their products on my '71 CS suspension rebuild; and, they have a telephone where carbon-based-units talk to you on the phone (if you like).

The database I have for Moog springs doesn't have F-85 listed, but it does show 5390 and 5374 were the two options for the other Cutlass models.

The specs don't appear to be very different between the two.
