Sounds like you have been following build as I used the same rear axle.
What are the specs on the front end?
High pinion (8 in.), ARB w/5.29s. OG Longfields, Marlin crossover w/25mm pins, 63in. WMS. Was originally going to run leaf springs up front but have gone away from that idea. I figured once it was done and I wheeled it with the leaf setup I was going to want to link it. So rather than do the front twice I'm installing a 4 Wheel Underground 3 link.
I purchased the front axle about a year before the rear. At some point in that year I decided a V8 would be put into it in the future, so I got the FJ80 rear. I'm a long ways from the V8, lol.
