C30 Idler Arm - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I need to do some suspension work on my truck and it looks like parts might be more expensive than I had thought. Does anyone know if there are any differences in the idler arm on a 65 C10, 20 or 30? There are 2 that I have found for a C10 - with and without a frame bracket, but no one shows one for a C30.

I know I can swap the whole front end from a 73-87 but I don't want to do that. I have no problem with the front drums and the truck drives great. I just want to replace the idler arm for now.

Can anyone with a C10 or C20 post a pic of the idler arm and take a couple measurements. I need to know distance center to center on the pivots. This is the one that is on my truck and I want to see what the difference is.

Does anyone know who makes suspension parts for LMC. Im going to order an idler arm from them and Im curious about the quality. I checked with my local NAPA and Carquest and they both want around $200 just for the idler arm. LMC has one listed for $40. I cant justify spending $200 on something that will only get driven for fun. Hopefully someone has experience with LMC suspension parts.

Installed my new LMC idler arm today. Seems to be good quality. The new one has grease zerks and the old one didnt. I've got an extra $200 for parts now so Im happy. For anyone else that is looking this one is listed for a 3/4 ton. The few places that list 1 ton parts had the same part number.
