LS1 coil packs - supplied by Shannon at Bursons
MSD LS1 streetfire leads - supplied by Aaron at VPW
Custom bracket - fabricated by me and TIGed by John
I was going to get a pre made bracket like the spec one but I don't think it will work with standard length leads. Hence why my bracket was the coils on an angle to allow standard length leads to reach spark plugs 1 and 4.
