decide the rake angle you want, set the frame at that angle before putting the MII in. adjust the rear suspension after the front is done so you end up with that ride angle. different springs, blocks, whatever.
get rake angle set, get the frame levelled side to side, then get front cross member levelled up at the new axle centerline. tack it in, assemble the upper mounts in their location and tack them in. mock up the rest of the front end stuff, minus brakes, shocks etc.just the basics. control arms, spindles and hubs. level up the lower control arms so you know the ride height, use some threaded rod to keep them where they need to be and stick a tire on to see if thats the ride height you want. it needs to be the tire size you will run in the end. if you like it, do a quick check on the camber/caster to ensure everything is where you need it and the tires are gonna look good in the wheel openings. if all is good, tack the weld on stuff to the frame. dissassemble the parts and weld in the weld in stuff. you are committed now so you should be all excited and giddy etc. now finish installing all the brackets for shocks, stabilizer bar, brake hoses etc etc. notch the frame for the steering rack tie rods. assemble everything in mock up without torquing it all for final assembly, see if you like it.
