I have one, less than 6 months old, went with FAST system. No wires cut, comes with BuickGN engraved shaded hood, "Buick Motorsports". $200/shipped. Let me know.
I have a new set of ARP head studs #123-4003-86/87 buicks-$60. shipped., also have 1 set of #123-3603 6pt head bolts for 85-87 gns, and a set of #123-3703 12 pt head bolts for 86/87 gns.
I've got a 20 row stock location IC for sale on here. 20 row stock location IC
No problems with it and just sold my car as a roller and have a powerstroke FM on my GN or I would definitely use this 20 row.
Bryan in KC on this thread knows me (at least knows who I am from BG) if you want a reference..
