... Have you considered Toyota outers at all? You can run them on a D44 center if you like, then you get 4 piston calipers and 45 degree steering with RCV's.
Ok. What I was thinking about was a D44 with heavy duty inners and Reid Chevy outers and RCV axles. After a lot of research last night I figured out that ain't happening. There is way too much crap involved with RCV and D44 Chevy outers. Which sucks 'cause that appears to be a real solid setup.
The solution to this problem is to go with Ford outers, hubs, brakes, etc. Except EVERYTHING I already have is GM and I don't want two vehicles with completely different stuff. While I don't like the old D52 OEM materials quality, the design is good and there's a ton of after-market support for that stuff.
As for Toy outers, by the time I spend enough to do that with RCVs I could do the D60 outer conversion and still have my GM D52 and 6x5.5 setup. The D60 outer conversion is stronger than the Toy setup and still gives about the same 45 degrees. For whatever that's worth - you're not going to do 45 degrees on anything less than full width axles and no fenders.
The idea is good, but technology has long since passed that design by.
... I don't suppose you know about the Dodge 1500 BMC crossover? On PA_JERO's rig we are going to run a late 90's early 00's BMC off of the 1500 to power his Wagoneer brakes. He's running Wagoneer front calipers and Montero Sport rears, I imagine we won't be as lucky with this one and will probably go through a series of trials to get it working correctly.
Spent most of today going through brake stuff including this.
Mitsubishi 3000GT non-turbo 1" brake master cylinder 1.00 40.00 M10x1 IF M10x1 IF
Mitsubishi 3000GT VR4 w/ABS 1 1/16" brake master cylinder 1.06 40.00 M10x1 IF M10x1 IF
Dodge RAM 1500 1 1/4" brake master cylinder '98-'0? RAYBESTOS MC390426 1.25 M12x1 IF M10x1 IF
Dodge RAM 1500 1 1/8" brake master cylinder '95-'96 RAYBESTOS MC390259 1.13 40.00 9/16x18 IF 1/2x20 IF
Dodge RAM 1500 1 1/4" brake master cylinder '97 RAYBESTOS MC390257 1.25 9/16x18 IF 1/2x20 IF
The Mitsu booster has a 40mm x 14mm ID bore. Measured that today. All three of the RAM BMCs above have a 40mm OD bore as far as I can tell. The 1 1/8" for sure does - referenced in everyone's docs. I presume the 1 1/4" BMCs do also - at least they look like they do.
The sucky part - as you pointed out - is the SAE fittings. But, companies make adapters, so ....
Note, the first RAM BMC is metric. Unfortunately, both ports are not M10s.
None of the RAM ones have fluid level sensors?
After sorting through calipers and BMCs all day long, I think I have the setup figured out for this build. Late '70s metric Chevy 3/4 ton 3.15" front calipers, late '90s Explorer 1.88 rear calipers with the 1 1/4" BMC. The alternative is a 2.94" front caliper with the 1 1/8" BMC but I don't particularly like the numbers, especially for the rear.
Front 3.15"
Required Brake Torque (front) (in. lbs) 52,193
Calculate Brake Torque (front) (in. lbs.) 51,900
Rear 1.88"
Required Brake Torque (rear) (in. lbs) 5,505
Calculate Brake Torque (rear) (in. lbs.) 16,284
Hydraulic pressure: 1370 PSI.
The Wagoneer uses the D52 brake calipers and rotors. Same setup I have on the '97. I think at some point the Wagoneer goes to metric D52 calipers so you might want to check that out.
What ratio brake booster are you going to use?
