Racers Edge shock caps

[The Crawl Space]

I've been working with these shocks for a bit and they do well for the price but recently the plastic shock tops that sit in the cap have been breaking.










I was told by a friend that these are modeled after an HPI shock possibly from the savage truck so I looked there, I think I found a parts tree with the pieces but its $12

I'm looking for either replacement pieces and ultimately a full plastic or aluminum shock cap with a one piece ball end shock cap.

Any help is greatly appreciated.
