Funrover: The axle is wider on a coiler but with some cutting and welding it could be done. It has been done. I've often wondered if a coil swivel housing would fit a leafer swivel ball. I've never had the two side by side and I'm sure this has been tried before so I never pursued it. if it would work it would be an easy conversion though.
Seriessearcher: Yup, many miles on the drums in the 88 and never a problem, even heavily loaded. Disks are cool but I'll have enough money and thought tied up in this truck just doing what I'm doing. It's alway something I can do later if I'm not happy with the drums.
Dave: Drop me an email and I'll send you some pictures. It's a pretty easy chop and weld if you have a tig.
Linus: I'm using a stock NADA bulkhead on a Stage One frame. As you know that bulkhead is deeper to allow room for the 2.6 6 cyl engine. It's this depth that'll give me the extra room for the 5 cyl. The Stage One frame also has the first x-member 4-5 inches further forward than the Series frame and doesn't have the huge welded second x-member that the Series frame has and only a small bolt-in x-member further back. That gives me 6 feet of unobstructed frame length to play with. As long as I have the space between the bulkhead and the radiator (which I do) everything else will work. I did knock the inside corner out of the passenger side foot well when I welded it in to give me a little extra room for the turbo/exhaust. If you look at that picture of the bulkhead you'll see that. Except for that the bulkhead is stock.
