Sewlow if you have a us address I could ship them to it probably wouldn't be too bad.
A couple of years ago, I would have been all over this. But any 4.3 mods are not gonna be happening now.
Buddy's got a 5.3 in his shop that more than likely is going into my '98 this winter. Once that's done, I may sell the truck, & use that $$$ to finance an LS/T56/EFIlive in the '97 on a 4/7 drop, my 338's, a hydro-boosted front big brake conversion & '95 Impala SS rear discs.
Considered just parting out the '98, but I've had people threaten to throw wrenches & stuff at me from across the country if I did that!
