On the 85 Mustang, to attach the Backrest, you have to lower the Backrest push in the middle and raise for it to latch.
The seat part, I tried many different ways to latch , the one that works is, take your shoe off and use your foot and leg pushing in a downward back motion. Very easy.
We have a 100% chance of freezing rain tonight.
