Has anyone used these? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought some nice ‘72 door panels that I am going to use in my’70. Has anyone used the extensions for the window cranks and door latch relays? Did they work out ok? Here is a link for what I am talking about:

Sorry I should have tested the link. Thanks Pat!

Ebay links don't seem to work anymore for some reason

I would be concerned about leverage on the regulator if the mechanism tightens up. Looks like it should do what its designed for, but at what cost

**70STOVEBOLT** · 02-07-2026, 11:13 AM

I would really only need them on the door latch relays, as I have already converted a pair of regulators to power for the windows. I am not sure how easy it will be to find ‘72 relays.

**70STOVEBOLT** · 02-07-2026, 11:14 AM

The shafts are 1/2” so I think they are strong enough.

I'm assuming these would be needed if going to a thicker door panel?

**70STOVEBOLT** · 02-07-2026, 07:41 PM

Yes that’s the plan, to put ‘72 door panels in my ‘70.

Caution on fitment of aftermarket 72 panels. If you plan on using original faux wood inserts, and SS trim ring, they don't fit the aftermarket panels correctly. I attempted before I realized my panels were salvageable with some effort to clean. The aftermarket panels from classic industries fit the door but inserts from original were a no go. At the time there was a vender selling some at 2 or 3 times the price claiming correct fitment. That prompted me to re think restoring the originals. Glad I did.

I will be using original GM panels. Good info though, thank you.
