Customs 55 chevy build

im building a 55 chevy wagon. n i notced that the 55 pontiac is really similar. it basclally looks like the same car just with a diff frontend and trim. i was wondering if anyone has done it and how hard would it be to put a 55 pontiac grill on my 55 chevy? and the pontiac tail lights

 

The canadian pontiac is on the (same as) chevy frame/platform but american pontiacs have a longer wheelbase making a longer frontend/doghouse than chevies.
Heres a canadian pontiac laurentian.

I think this is what "all" the 55 pontiac "wagon" tail lights look like,(not safari/nomad type poncho wags) They should fit in your existing openings. Here is a canadian delivery.
