The bracket for the front mount on the front seat for a 1954 chevy car. I have a 53 and a 54 here and no brackets to be found. If you have one or a pic I would love to see what they look like.
I didnt know if the 55 piece would fit, because I don't know what the original one for the 54 looked like.
I'll look in a few boxes this morning and see if I can find mine and get a picture . Or measure the floor and seat then you can figure out if the newer ones work.
This is a '53. Different left and right, I believe this is a right. The holes are 3 & 3/16ths apart, and the step is 5/8" and 7/8" respectively. The strap itself is 1" wide.
