81 ford courier diff been changed to falcon stud pattern, 3'' studs, 30 spline axles, s13 silvia callipers & handbrake cables, au disc's, 4.1 RX7 FC3S Series 5 Viscous LSD, new bearings, 1370mm, just built it for my escort but now im thinking of mini tubbing it and building a shorter diff the housing it self bolted straight in to the escort no mods. anyone interested ?

Rough idea of price? Will this bolt straight up to a early mk1?

pretty sure it will I think the mk1s are the same as mk2 but i'd ask about and it owes me $1400 so that's about the money i'd be after
