K10 front axle bump stops - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This should probably be about the least of my worries, but it's been eating at me for a while. When I was cleaning up the front frame of my '68 K10 a while back I ended up pulling both of the bump stops out. One was already destroyed, and I did the second one in while removing it.

I haven't been able to find any replacements for these things anywhere. Are they just not made anymore? I've found some that look kind of close, but I think they are only listed for the back end of 2WD trucks so not sure if they would work.

Plan B is to switch to the newer stud mounted ones that seem to be widely available. I figured I would ask here first in case I'm just not looking in right places...

The rears look the same to me. I believe the bolt in style is listed for front and rear of a k10. If I were in your situation I would order the rear push in mounts from a place that allows returns and see if it fits. About $20 ea from what I have seen. If they do not work return them. Even with shipping back total loss will probably be around $30.

Thanks guys. I guess I won't be out too much to find out. Some of them have dimensions listed, and they all appear to be a good bit smaller than the ones I pulled out. They are probably cosmetic at this point anyway, since I put taller springs on it.

Edit: The MOOG K6607 is what I ordered. It looks to be a little taller than the others, and was available on Amazon of $15/pr. I'll try and remember to update this once I see how they fit.

I know this is an older thread, but I just replaced two of these on my 1970 Blazer that did the same thing due to being 53 years old. NOS on Ebay is pretty easy to find.

GM part number 3843849. Fits 1963-70 trucks
