Skyjakcker also makes a D45 4. 5" spring too... $156 at Summit. Might wanna check with them, I'm sure that would stretch the control arms, track bar, etc. . too far outta whack. But it's worth looking into. I know I have seen 3rd gen's with D25's and 35's or 315's. No rubbing with the alum wheels, but the steel wheels will rub a lil.
Hey Ken As for the gauge install. Like Steve and Paul said. Just tell us where. There's plenty of experience to give advice and tips. I'd like to see another get together soon. I missed the last one, and it does apper that we are kinda dwindling off. I hate to see that happen, we're a good group. One tip I'll give you now is to call Piers and get their boost bolt for your boost gauge. It will simplify installation. Also make sure you've got a tapped banjo and new sealing washers from Cummins for the fuel press gauge (unless you're hooking up via the schrader valve... which I'm not sure if you have or not... I can't ever keep that straight
).
Hey Mark (or other stack guys)... What is the purpose of the box steel for a stack set-up? It would seem to me to be very in-efficient. They do look fantastic, and I see lots of people doing it... Just curious.
Anybody find Gap a new truck yet? Poor feller...
