So my 63 had a single hole in the firewall but my 62 has 2. It was a dual resevor one being for the hyd clutch and the other for the brakes. Right now I am planning on running the truck with a 4L80E auto behing the LS1 but at some point I may convert it to a M6 which would require the hyd clutch.

Is there any boosted dual resevor set up aroud that also has the clutch master? I figure I could use that one ad if I ever wanted to run the M6 the clutch master was there.

I also thought about cutting the firewall and welding in a later single hole 2 bolt firewall piece but that kind of defeat the esay M6 swap.

Any ideas?
