74 vette with stuck seatbelts

I can't get the lap belt to give more inches. It seems to be stuck in its roller under the seat. Is there a trick to this or are the rollers rusted?

HI there,
Normally, all you can do is replace the roller and belt.
Sometimes those teeth get jammed and then just break apart with enough force.
These are readily available, so you shouldnt have too much of a problem getting them.
Allthebest, c4c5

remove the seat and remove the pan covering the roller. i'de bet its a ball of rust. i was able to wd40 the hell out of mine and get them working again but it was not easy.
