MotorbyMotor Universal Window Crank Shaft Extension Compatible with Chevy Camaro Corvette GM Buick Pontiac Olds, Door Latch Shaft Extension

Worked as they say they do!

There is nothing but praise for this product . My project was finished successfully with this product.

I needed something to bring my door handle out around the power window add on the previous owner installed. This does the job just wish the alan screw was pointed on the inside to bite into the teeth I stead of flat. Just have to tighten now and then.

Useful doodad... buuuut.... In order to get this to work properly, you need to drill a hole in the original spline for the worm screw to bury into, otherwise it just works free. It also needs opposing worm screws, I am going to mod mine to have an opposing screw, the single wormscrew makes it sit off kilter. I suspect you can make something better.

has no grip just slips

Product fits older window crank handle, sloppy and loose fitting even after tightening. Does the job but will seek alternative solution.

if i can return it, i would. product is not universal as it states it is. i want my money back. seller never contacted for a refund or anything, waited until the 30 days were over to not be able to return it. i want my money back!!!

The inside of the window crank should be grooved to fit the window crank design verses using a weak set screw. I had to countersink the shaft for the set screw to get it to work right.

On Gen 1 Camaro/ Firebird with Deluxe door card I found I had to cut the knurled section off the original window winder shaft and die grind a small flat for the grub screw to locate...otherwise the winder handle is too far from the door card ..
