I picked up a decent 77 t-top car but it is in need of a couple floor pan patches. Who makes the floor pan for a 77? I can normally find any part needed but this one eludes me. Also will a Monte Carlo/Grand Prix/Regal pan fit?

 

You will find somewhere between little and no aftermarket parts for a 73-77 A-body. Just not a very popular car. You will propably have to make patches or cut out of a good floored car. Around here a parts car could be had 500.00 or less all day long.

The only place that might have floor patches would be Sherman. You might try them.

 

Here ya go (keep in mind that the floor pans are the same on Chevelles):

Keep in mind that these patch panels are all stamped by the same one or two factories in China and they all fit poorly, so just find the lowest price.
