Making new option list

[MrGoodpliers]

I'm working on a '69 short fleet, making a CST out of it. As most of us do, I'm adding a few things that were not original. If someone could help me out with some option codes, I'd appreciate it.

396
headliner (was there an option code for this one?)
vacuum guage
Vette-style steering wheel (also unclear on this- "cushion grip"?)
cruise control
4/6 drop--- HeHe

Don't know if I'll ever find the cruise or be able to afford it, but I'd still like to know the code.
