OK, so, long story, but I have here a non divided HKS cast mani for an FC, and HKS 'Standard' Wastegate.
Outside, I have an FD, which I intended fitting a GT35r to...

I've searched loads, but I can't seem to find a definitive answer - will this combo fit my car? Or am I going to have frame rail issues?

RHD car BTW, but that will only affect DP I guess, and we can get around that

 

Assuming that the 35r is divided, the undivided manifold is gonna hurt the spool. As for the fitment someone who has one will have to chime in.
