F- m body rear suspension exch.

[CM360]

Can you put f body rear springs on m body. Want to see if caltrac would fit. Calvert does not list the m body.

 

[MiradaMegacab]

FMJ springs are 58" long
With a 24" front segment
And 34" rear segment

 

[DCAspen]

Yes,The rear suspensions are the same.

What leaf packs were on the common F or M? I count 4 on my f coupe, but there is a set in my shed with 7? I think. I don't know if they truly were from an FMJ, but the measurements check out correctly.

My J-body has four leafs per side. The new epso springs for the Aspen are five each. Stock was four each IIRC.

 

[Jack Meoff]

Stock was four each IIRC.

X2.....4 was standard.
My Fifth has five because someone added a hitch and an extra spring.

5 leaf are heavy duty, 4 leaf are standard. The 6 and 7 leaf units are custom, and were available from a couple of catalogs back in the day. F, J and M bodies have the same suspension parts front and rear.
