J body and M body floor pans

[chmirada]

Question, does anyone know for sure if J body and M body(4door) floor pans are the same ? I stripped several back in the day but i never paid close attention. Don't know for sure but im thinking I may need floor pans due to the T tops leaking . Car is still in tack, need to remove interior. Your input will be appreciated.

They are similar, the seat holes are different and some difference s in front of the rear seat. That said an M body floor would be perfect for replacement of a rotten J body floor. Just make sure to measure mounting locations

On this topic, are the F-‘s floorpans the same as the M-‘s?

Four door pans are the same, enough.

Ok, the reason why I asked is US Car Tool has a set of subframe connectors on their site that are pre-cut for the F-body floorpan
