Thx guys very helpful.I just wanted 'eye-test' info for now because he's wanting enough for it that unless it's a Z or a BBSS car I'm not even going to bother with digging any deeper.I knew about the interior markings but didn't know if they were always marked,good to know that barring alteration it's a good place to start.The fact that it's a single fuel line with multi-leaf,not sure if it's 4 or 5 leaf,(if factory) car looks like it narrows it down to a Z or BBSS so that's good.
IF it passes initial visuals I will take pics and post them...again many thx.

. I'm going to go look at a November of 68 car and was hoping someone could give me a link or tell me how to 'decode' this car since it is 'pre-X' car.He told me he has the Houndstooth Interior and that it has the bigger fuel line and large hole in the fire wall,whatever that means,has front disc brakes,multi leaf 12 bolt rear end and is a four speed console car.He also said he has a DZ motor that has been rebuilt at some time or another that goes with it.
