whats the difference 49-54 chevy

what is the differences between the 49-52 and the 53-54 chevy car one peice rear bumpers? is the overall dimensions and design the same?

 

'49-'52 - front same, rear same. '53 front - 1 year only. '54 front, 1 year only. '53-'54 rear same. Mount holes for license brackets vary from year to year.

 

sorry let me clarify. what are the changes between a chevy 52 rear bumper and 53 rear bumper? are they the same?

 

no, they are not the same.

You can get new chrome one piece bumpers for both types now...

 

what about front fender interchangeability?
