Gen X RF Upper

[HuckleberryB4]

I have an S7 Smack car that I am putting the wider Gen X RF on. Wondering what length upper MB calls for on the Gen X cars? I was planning on spacing out my existing, but it needs replaced anyway, so I'm going to order the correct length. Thanks.

8.5" is standard RF upper for a GenX
