My dog might get more enjoyment from my TRX vehicles, which is what led me to this mod. At first, the original body pins kept pushing too far in after a session and were hard to get out. This pointed me to some pins I had used many years ago that worked for me:
To make them work, I had to remove part of the body cage in the rear. The reason I didn't leave well enough alone was because I was concerned of the sharp point on those pins hurting my dog. I use the Proline thumbwashers on my 1/10 Slash 4x4 (another toy of his) so I wondering about using them on the Summit. With some trimming of the washers themselves, some screws from Home Depot and the aforementioned cage trim, I made it work:
I plan to add them to the front as well. I'll need to get another Proline kit to get the extra washers again.
