Big torque on the axle for sure. Just curious myself as to what maintains the bearing float. Preset within the bearing?

What you end up with for PSI will be determined by the bore of the M/C. The bore/stroke of the master will depend on flow requirements needed to keep a decent pedal hieght. I do not know the specs on the Jag calipers for that year and haven't gotten that far on my build with the mid 80's one I have in the works. I have done non Jag conversions to rear disc using a 1" bore M/C with good results. An 1-1/8" bore would be a bit more pedal for me if I thought it was needed but would need more leg at the pedal. The math is tedious but doable to figure out what you need. Perhaps one of the guys have some decent links for it. Boosters do not really increase the pressure so much as to make it easier on the driver to apply it. They enable larger bore M/Cs that move more fluid to be more comfortable to use. You proabaly know all this already anyway. but the residual valves would keep 2lbs of pressure on the calipers already , so to say it takes 800lbs to activate them sounds goofy to me. jm2c
Edit: Being a Pick Up and firewall mounted residuals would probably not be needed.

I'm glad to see that guy is protecting his hands. He will need them to read braille after he goes blind.

I have been under the impression that you have to dump BIG bucks into a 200R to get them to handle ANY HP. Would also have to lengthen the driveshaft compared to the 700/ 400 swap. I run a 700R with 4:11s and with some pretty short tires. While it is not really comfotable at 80mph it does OK at 70. Just seems to me keeping a taller tire and staying with the 700 would be a better deal than the 200. For cruising highway  that 400th would like to be infront of some different gears especially if you are going to pump some HP in front of that.

Just a curious question for you guys. With that double  frame LCA in Ralphys Cobra pics and the addition of a Watts link. Would that at least partially replace the need for a trailing arm ? Sorry for the thread hi-jack . Was just a quick thought.

That thing is Nasty in a Very cool way !  Got more pics ??

The LCAs are not solid on the yoke ends . I'm not sure if you could remove enough stock to get that square you are after without compromising some strength. Maybe it can be done.

Ok that looks like it really. That hub set up sure makes it look like the geometry would be wrong though the way the pics hide things.

I don't know anything about the knock off style hubs. Are the uprights stock or shop made? I'm curious as to how the LCAs hook to them.

These sleeve type bags came with the van body when I bought it. I don't think they they are an overkill by any means. Definately need a swaybar on the rear as it acts like a Weeble when aired up. Just figured if it doesn't work the way I like ,I'll go back to the coil overs. Right now it also has air over leaf springs up front. That's a little weirdness unto itself also. 

This is a little off topic, but where did you get the wheel flares and chin spoiler?
And welcome !! 

I ran into the same thing on mine, bracket bolt. I tried all kinds of heat with an easy out , even tried the welding the nut on thing a couple times. Maybe a I should have tried more because it was a real pain jigging it up in the mill to bore the hole out.

An internal gusset sounds like a good addition and will keep a clean look. I would imagine the inside of a casting of this sort may be to uneven to get a solid inner sleeve in place. I have welded cast steel and have watched pros who know what they are actually doing pull it off ok. I have just never tried it in a place where the abuse factor is this high !

The stamped one looks like it would be a bear to shorten. Cast steel can be welded and with the right added support may be a way to do it. but it requires preheating and all the special touches to do it right. I would talk to a pro- welder or someone in a tool and die shop before trying it.

I'm not very familiar with 4x4 IFS stuff, but my thoughts took me to things like a geo Tracker , then Nissan. The 95-96 Nissan front center section looks like it could be narrowed up, from the outside anyway. I have no reference for the size of the components tho. Fun idea, but will definately take some research.
