Rustler Chassis - Que's & Triangular Pieces

There are two triangular pieces with the chassis. I assume they are to hold the rear shock tower, that's where they seemed to fit best. The plastic shock tower lines up with those holes anyway... hopefully I have them where they belong. I had a lot of extra screws and pieces that hopefully aren't needed.

Other question is... Camber links & Extended arms... Are there any replacement parts for the extended arms? I'm going to attempt to create my own tomorrow from some scrap aluminum I have in the shop... basically they just need to hold the wheel alignment.

I ordered a rear shock tower with my parts, but it wasn't in the box... so I'm not sure if the rear fit either, may need to make a second set.
