There's a place called Northland Fasteners. They have a good selection of body clips, pins, etc. For some they even show a Mopar equivalent #. The bumper ones I got were perfect. The fender well were not, however that was not their fault, as there was no cross-reference for them and I figured wrongly on the number. The part numbers that worked on my '98 are: N18269 and N18327. I'm not sure which one was for the top or bottom, but the *69 has the larger head diameter. Good luck.
Website is Northlandfasteners.com . I tried adding active link, but page here is adding to it, therefore it is not working.
