Highlander experts....little help?

[Highlander72]

Hi, just bought what I'm pretty sure is a '72 Highlander. Truck is white/orange/white, 350-4bbl, A/C, etc. Has an white vinyl/orange plaid bench seat, but the plaid doesn't seem to match up with what I've found around the 'net. Glovebox sticker says "Orange Highlander P"....as in plaid? Package?? Door panels appear to have been white, now painted black.

Also, truck does not have tilt steering, word around the 'net says it probably should. Have also heard about 3 levels of Highlander package, A, B, and C?

I'm attaching pics of the glovebox sticker and upholstery. Any help would be appreciated!
