I have some NIP chains in my parts stash, I can send you one for the price of shipping from Canada to USA. I can probably send it in an ordinary envelope between some pieces of cardboard, without even any Customs hassles. PM me if you're interested.

When you said the sound happens at regular intervals, and seeing the chain with that wonky link, I agree it could be the chain. Too bad that replacing it is a pain, unless you detach a link and feed it through like shown in the manual. It's doable but you might have to use harsh language.

Thanks! I'll PM you on that chain. I got it figured out. It was that one link that was tweaked a little. It was binding or catching or something. I pulled that link off and straightened it out as best i could. It fixed the problem for the most part, but under power in reverse you can hear a slight "tick" every time that link goes through the front diff. I think Ill just replace this chain for peace of mind.. I took apart the chain at the top and then tried to feed it back through after fixing it. Fail! :!: :lol: I got it through the rear diff ok but once I got it to the front I managed to bind up the chain to where I had to take apart the front diff housing just to get the chain out. All in all, I only had to take half the car (i mean truck) apart. 8)

Progress update! :D I got the body today from TBG and rough cut the perimeter of it just to see how it will fit. The wheelbase is spot on and the width is perfect. This body gives it a more realistic scale appearance with just enough tire sticking out to give it a mean stance. I have to fab up some body mounts now and do some more trimming around the wheelwells, but I think this will work. :D

Here's what I came up with last night for body mounts. I wanted something strong and easily replaceable so I made some basic angle pieces out of Kydex and used them to mount traxxas slash body mount parts. It looks like it will work well. I plan on putting this truck to the test from the backyard to the track and I don't want the vintage Optima inside to be in danger of damage more than it has to be.

Nice, looks pretty much similar to the original Kyosho Rampage truck body mounts. In fact, I might actually like yours better, they're leaner and less clunky-looking. 8)
