have you done the seats and dash like that too ? Save wiring any gauges up !
Excuse my ignorance but are ABS callipers built with separate circuits for the pistons ?

Is it worth considering swapping out the axle to a later one ? At least that way you can find people to do the install and any future repairs you might done.
