Just so you know I tried putting those headrests on my non headrest seats and could not do it because the frame of the seat was different and did not have the holes to accept them and did not want to cut up my redone seats to do it so im just going to redo the seats with the headrests
Do you need the parts for a disc or drum brake car. Disc are a different length bolt due to it being a 5 1/2 wheel. Also the board should be a small round one.
