van tilt parts

[t300]

Lucked out and locally picked up what I believe to be a 73(ish) van tilt. Sticker on column reads 7827343. Are the parts mostly specific to the van column or are some interchangeable with the 68-72 truck columns? Looking for the white plastic 'pointer' (does it have a cover?) as well as indicator lens for my 4L60e. It was apparently in the guys basement for 15-20 years. Feels pretty tight so I don't think I'm going to disassemble, just a fresh coat of paint.

thanks!
