The Pinto station wagon is a great filler for 28-32 Ford coupes and maybe even 33-34. Just remember to do your layout sideways on the roof. In other words, the FRONT of your Model A insert pattern should be laid to the rain gutter side of the donor roof.
The Pinto/Bobcat roofs from 1972-80 are not ribbed. Perhaps the Vega is but I haven't seen one in so long I can't remember. Heck, even the Pintos are getting scarce.
last one i did, replaced all the wood and used a chevy M van roof panel from drip rail to drip rail, from visor to soft top attachment at the rear then blended the rear upright "T" strips into the roof.
