I belive you have make an error of topic 
i speaking of trampa box flex here . It not had an xt90s
Ja sorry 
wrong answer to wrong topic
You can choose the end caps as option when you choose the length. There is a special drop down menu. But it add some costs on top
That’s correct. The Caps are CNCd from solid aluminium and are anodized black. They come with rubber grommets to feed through all cables. This kit allows you to make a custom length impact safe battery tray. Internal length = chosen tray length - 20mm.

other question . I want to buy a 66 pulley . Can you say me what’s size strongbelt to buy . My motor mount is the little , for gummies . thx
That is no good idea! You want the longer mount and a 460 Belt. The short one only works with the smaller pulleys. There might be a belt that flits, but tooth intermeshing would be terrible.
Frank
what would you say by that ? the strongbelt thooth can’t fit , or destroys the belt faster . the contact of the teeth of the pulley and the belt is not sufficient. What the belt jumps or breaks?
If the small pulley sits to close to the big one, the small pulley has little tooth intermeshing. Either ad a idler pulley or use a longer carbon panel.
On the small panel you can ad a idler pulley from our shop and go with a 425mm belt. you would need to make yourself an axle spacer for the idler to centre it.
