Kk Rear window glass lift fits on Kj?

[blackhawk]

A local vendor is selling a pair of Mopar rear glass lifts under number 57010050ac and says it fits on kj.
Looking at the part number and doing some research, I realized that this is almost 1/2 inch shorter than Kj's.
My fear it's that it won't be strong enough to pull up the glass.

What do you think regarding the weight of both glasses? What's the heavier?

Thanks!

I don't know what they are like but I bought a set of KJ ones on Ebay and my rear glass is now like a medieval weapon! It flys open, I'm going to have to change them before they smash the glass, too much power isn't a good thing. If it's a local vendor than at least you can take them back if they don't work/fit.

It happens to me around 8 years ago, but they didn't last what I expected. What brand did you buy?

Black ones! Finest Ebay had!!
I'll have a look and see if they have any marking on them, I see some of the sellers are quoting the force of the gas struts now all we need is the original spec.
