Need new window regulator for 79SC Targa - questions.

[Johnny Graham]

Hi folks.

My left side regulator (manual not powered) is notchy and jumpy on the last few turns upwards - and I need to lift the glass the last inch manually.

I have removed the regulator for inspection, and the teeth on the last quarter of the arc on the drive gear are badly worn. I tried to file them back into shape but as expected it still jumps.

So, I am looking for a used replacement, but getting confused over part numbers!

According to the parts PET, manual and powered are different, coupe and targa are different, and F and G series are different. Ack!

My question is - are they interchangeable in the real world? Do F regulators work in G series? Do coupe regulators work in targas? I know they are different p/n's but a search suggests 65-83 all use the same part..

Also is the drive gear (I mean the longish metal arc shaped piece with teeth) replaceable on its own maybe, has anyone done this?

Search hasnt helped, thanks for any advice..
