Bagged 59 6bt ifs options

[greengrenade]

Im bagging my 59 apache shortbed and i wanna do a 6bt swap as well. im gonna fab a basic chassis out of 2x5 box tubing for the main rails, 4 link the rear and build an x member to increase the strength. My problem lies with the front end. I need an ifs setup thats air ride compatible and can support the 1200 lb cummins. My first thought is using a 73-87 c30 front clip and narrowing it to fit but id like to see if theres any more options. Id like to have rack n pinion if at all possible. Any one have any ideas? Any aftermarket options? A 4bt is outta the question, there too damn noisy and vibrate like hell. Any info is appreciated
