1 inch throttle body spacer

One question - will it just bolt in there no problem? It doesnt look like the fuel lines will like it. Any thoughts?

Actually, the TB spacer will fit fine, its ur throttle linkage that will be messed up. That 1" spacer is to high and the throttle linkage has to stretch in order to hook to ur TB unit and it holds the throttle bores open when u get everything hooked up. What u need to do is either get a .5" spacer if u haven't got the 1" spacer already or if u have the 1" spacer already like I do, I took the back bolt of the throttle cable bracket and got a dremel tool and made drilled a longer path for the bolt to move back in forth for that hole, so u can move the linage forward and then tighten the bolt down like that. Do u kinda get what I am saying? If u don't, maybe someone else could explain it better.

what i did with the 1" spacer was move the throttle cable to where the cruise cable was on the bracket and put the cruise where the throttle was since its longer. u gotta file the hole where the cruise was otherwise it wont fit...ull see a wedge on the left side of it. then everything snaps in. i needed to take off the bolt holding the fuel lines on and leave the lines just sitting there not bolted to anything cuz i didnt want them to stretch or anything.
