Ok, I'm ready to actually start building my SLC Superlite. I have it disassembled and cleaned up and of course I've been ordering parts in preparation... Now, what do I do 1st? Do I start installing heat shielding and sound dampening or do I start building, then take it all apart and do heat shielding and sound dampening after I know where everything will go? I don't want to screw up the very fist step! Any help would be appreciated!
