These are 2 frame mounts for the 455 motor. If I am not mistaken they were used to put a 455 Buick in a Regal car or a Monte Carlo around 1980 . So I think that would cover like 78 to 86 " G " body cars ????? Anyone know for sure ?????
They really look like the T/A frame pads I bought for the 1964/455 conversion. The motor mounts are of course aftermarket. ws
