On my J-H, I used a RX2 rear axle with 1st gen RX7 limited slip and rear disc brakes. It's almost exactly 1/2-20, yiu can run a 1/2-20 tap into the threads and guess what? MG inner tie rods have a 1/2-20 thread. The Miata outer tie rods have a 12mm fine thread. You could save some $ out of the box by keeping the stock spring pan setup, it's not real difficult to change springs with that design. Then you can make a set of mounts like the tube shock conversions use. Fab up an upper C/A mount like the one MGBryan posted a pic of, not difficult. That's not as difficult/expensive as it sounds. If it were me, I'd make the upper C/A threaded so the camber could be adjusted that way. He should be able to give you some pointers. IIRC Keith on this board used Miata stuff on the front of his LS1 MGB GT (actually, that's his wifes car. While not exactly a bolt on, it's not overly difficult either. I have adapted Miata uprights and brakes to both a Spitfire and a Jensen Healey. We have a load of parts to toss into the mix, but need a little direction ahead of time as to what will or won't work out. I know that I'm not the first to try this, hoping for a link to a build or maybe some pics of the process under way. Most likely based on the MGB or Mustang II assemblies and moving on from there. Hopefully somethings can be combined into a set-up that will work.

Another set of adjustable coil over shocks, Bilstein shocks, Konis, GR2 gas adjust, sway bars and install kits, various rated spring sets, panhard rod set-ups, traction bars, disk brake assemblies, various steering racks, and such. We have a lot of extra parts hanging around though. And even that's kinda high for just the front end. If I can mix and match components and maybe salvage a few bits from one of the other cars, fabricate what's needed and all, I'd like to get out of this for $300/$400. I can place the MGB assembly in front of it and see what it's going to entail. I really won't know anything until the frame is here tomorrow and sitting flat on the trailer. I have a complete MGA front end to work with, I honestly wouldn't mind simply measuring everything up and welding the entire MGB front clip or sub frame to the MGA chassis if possible. That will help a lot, give me something to copy, hopefully. I was aware of the simple ones out there for the rear, didn't know that they were also available for the front as well. Thanks for the tip on the MGB shock conversions.
