I still dont see where you want to go...
you can go with lowring leafs and shackles and stick some dubbs under dere
or 15" leafs, rockwells, 54" boggers, 560 BB supercharged
all in all... you will find the gammet here but.. what do you want to do?
example...
just to show you the year interchangeability
my truck
1978 chevy
1979 gm d60 front
1976 cadillac eldorado rear disc calipers
1987 front clip
1984 bed
1991 caprice police 350 2 bolt
1996 tahoe vortec heads
1989 olds 88 relay pack (8 relays / 16 fuses)
1985 Jimmy hydro clutch setup
1988 chevy bench seat
now you do mention bolt ons for power... how much of a gain do you want?
I think since you are an old school mechanic you know there is no replacement for displacement.... bigger is better..... in either motor and or cam
although that doesnt always play when talking about lift.... yeah 15" lift and 54" boggers are better at boggs.. but maybe not for just trails and rocks.......
write down your goal and tell us...
