I have 7 NOS bumpers for 70-77 Cutlass or 70-75 full size. Part 407146. Reproduction are close but not exact. Photo shows current repops to NOS. NOS is very slightly longer and has grooves at the bottom. Repops are 4.5. Correct bumpers at $10 each if you need the bees knees. Shipping depends on amount requested.

 

Close up.

 

I know this is an old post but do you still have the NOS bumpers?

 

Probably but im at the Olds nationals until next week. Send me a direct message to dead@mchsi.com to remind me and I will look next week.

 

will do thanks
