Hey gang. Yesterday I was doing some clean-up in my 78 midget and I wanted to move the back of the seat up. I depressed the seat lever on the side and I cannot get these things to move. After getting frustrated I then tried to move the lever under the seat to see if I could get them to roll forward and no dice. It seems like they are all the way back and reclined back as far as they will go and might be bound up? I jerked on them a bit but didnt want to over do it and create another issue. Any ideas on how to get these free?
