Hey everyone, after way to many months my ls1 motor swap is almost done. There are a few things I need to do before being able to drive however. 2 of these I don't have an answer for and was hoping someone here could help.

First, I don't have room to mount coils 7 and 8 in their normal location. I thought this would be simple, find longer plug wires and mount them elsewhere. The problem is I cant find longer plugwires with the correct ends on them. Please tell me if there is a 4 cylinder msd kit or something out there so I can spark the rear 2 cylinders. I need about an 18" wire.

Problem #2 is I have a nice big vac leak at the rear of my intake (corvette ls6 intake) need to know what size vac line to use to seal off this hole (circled below).
