Sweet build. I’m wrapping up a frame off resto on my trusty 1990 f350 right now. I would go arb for lockers without a doubt. I put that same aero tank in mine and I guess I lucked out because mine came lightning fast and that wasn’t too long ago. Look forward to seeing the progress. i Usually ditch any broken plastic clips like those brake line ones and use stainless straps with the rubber liner and bolt them to the frame. Something I’d recommend that probably isn’t too late for you is to have aero build in a sump where the pickup tube sucks from. It will be right behind the axle so won’t get in the way of anything and will make it so you won’t run out of fuel until you are really out of fuel and will help not suck air on real steep or off camber situations. I’ve gotten a couple tanks from them and did that and the skidplate which is another layer of steel welded to the bottom. They will build it however you want for not much more money reallyThe new motor and fuel tank are still about 2 months out. The suspension mounts should be back from powdercoating this week. I'm in the process of figuring out which diff locker I want to use on the front, which wheels I want to use, what I want to do with the bed, and what I'm going to to do with the truck's interior. That's only a small number of the decisions I need to make - those just happen to be in the forefront of my mind.
Minor parts that have arrived recently are a Red Head steering box and S&B silicone cab mounts. Also included is a random photo of my F350 on some bias ply LT 9.00/-16's
