U have the f-41 suspension. It had boxed lowers and rear sway bar. Also, i'm not sure if the f-40 came with upper control arm re-enforcement braces or not but i know the f-41 has them.

I have a 4 door 72 chevelle with a build sheet. It states the f-41 suspension but has none of the equipment. It came from an old grandma and was in decent shape with a good original interior and 90k on the odometer.Someone along the way took must have taken the parts.

F40 – Offered since 1964, included stiffened springs and shocks with a .937" front stabilizer bar.

F41 – New for 1969, included the F40 springs and shocks plus a 1.125” front stabilizer bar instead of the .937”. Added a .875” rear stabilizer bar with reinforced lower control arms.

I believe the F41 package also included special rear control arm bushings.

12 bolt rear ends came standard on all BBs.

I think they started using control arm braces in 1969 as standard equipment and in prior years only on BBs and maybe El Caminos.

I'm no expert but here's my 2 cents & a bump!

My 4 door does have the frame braces still, but that's it.
