Hey,
I have a '70/71 backpad with a rest, and seat. The lower seat insert is basketweave, therefore does not match the backrest. But maybe you can work with that.
These are in generally good shape for 51 years old. Some cuts, and some repairs (adhesive, or whatever) will need done.
I will let the photos do the talking.
Pick up only in Catonsville, MD. Just south of Baltimore. I can meet within reason.
I am asking $100 for everything pictured.
