I saw the pics on a SBO in a 70 Cutlass, they hang really low, below the control arm pivots. Too bad they don't make a set for the SBO, good quality otherwise.

I thought the timing indicator was just missing off my 260 but there is a metal pointer there, looks factory. Set up for a dial back timing light?

We had the 267 till 82 then either the 231 V6 or a 305 chebby. I did see a 4 door Malibu with the 229 chebby V6. Ironically we also had the Olds 307 in some of the Caprice's like you guys.
