i would get on c10forum.com and just check out peoples projects if they have pictures of the suspension, should be a whole forum on 73-87s, you can tuck 24's but be a good bit of work. like dv8 said call suicidedoors up and explain what you are trying to do and they will probly put you a kit or package together. there are a couple different ways to do it. you have to figure out how you want the front set up, i would suggest buyin a new front k memeber which comes complete to lay the front out but i think thats just on 22s and i think but not 100% sure that it bolts in. The other way is you have to Z your front core support and part of the front frame because the crossmember under the oil pan hangs low and all the cuting and fabbing for bag mounts. For the back i would suggest a simple triangulated four link, but you can put in a brigde kit and do bags over axle or behind, relocate your gas tank or put a fuel cell in. (So a simple list to get you started is 4 airbags. id go with slamspecialties RE-7s up front and RE-8s in the back. you will need 8 valves or you could go with 6( 2 for front and 4 for the back), you basically want 2 valves per wheel that way you have one to fill and one to dump, but you can do just 2 for the front if you do just four valves then you will get a lot of body roll when you go around a turn. You'll need switches or switch box, i would go with 2 decent sized compressors, a water seperator for compressors, a bunch of airline, and a decent sized air tank or 2 tanks that way you arent running the piss out of the compressors. other than that just have to figure in metal for everything else. oh and sorry this was so long lol oh and almost forgot the most important itemssss, Brass fittings u need a million of them suckers. some advice...compression fittings from Lowes or Home Depot suck, 9 times out of ten you will blow a airline because they dont seal tight enough.
