1968 GMC Window Regulator Repair

[68gmcdude]

Hi... I need to replace the wheels on my window regulator. Looks like the originals were riveted on(?). What it is best way to replace these? Where can I get replacements? Are the new ones riveted on, bolt-on? Thanks!

I have seen the kits to replace the rollers but cannot remember where
But you are on the right track
I bought replacements from lmc and they are junk

The little roller wheels used to be a kit. I think Brothers had them before the Holley buy-out.
In the Arizona sun, the rollers break up and turn to little square fragments you have to fight to roll up and down.
I don't know if replacement rivets were included in the kit.
I do remember a Regulator Spindle Drive Rebuild Kit. It gave you a fresh gear and ballbearings inside that dome with the window crank shaft [bottom of your pic] but you had to reshoot the three tiny rivets holding it together. Since there's more profit in selling new regulators, that item vanished.

I bought the kit from Classic parts of America . Worked out very well comes with the rollers and the rivets the rivets are the hammer and dolly type . I used a cross pean hammer and a small socket to back up the rivet kit comes with the tool to start the mushrooming of the rivet

On my 1972, the gear was stripped, so no repair could be attempted. I used an aftermarket ACI unit from Amazon, and it's been good.

I just ordered some wheels from Classic Parts. Hopefully they work out ok. Thanks!

What is the best way to flare the rivets? They catch as soon as they start to flare. I've tried ones from LMC and Classic Parts. Both are the same.

If you have a set of Roll Pin punches that would get it started.

In a earlier post, I mentioned I had bought a pair of regulator gear repair kits. They had fresh gears in the metal domes and were to be secured by little rivets. Snap rivets might work.
I got them from Brothers [before the Holley buy-out] i think.
You might also check GMC Pauls, and Truck and Car Shops of Orange CA.
Winding back the regulator counterspring is daunting, and the reason I just bought a new regulator from GMC Paul.
