Does anyone know if our door hinges are similar to any other pontiac or other brand of car?

LeSabre, Park Avenue, Olds 88, Olds 98.. there'* probably even more that I'm not thinking of righ tnow.

What about a firebird or 300 c, because I have 2 vertical dorr kits for these cars and wanted to know if these cars have any similarities to a bonnie as pertaining to the measurments of the height the hinges are spaced apart and the spacing of the door jam?

Trig...your best bet would be to spend some R&D time at the junkyard.
