Yep, TRUCKLINE do a great job.........although I got mine done at Truckline in Perth.
Mine was also $350 fully fitted including front and rear uni's......DRIVE in DRIVE out
A big ass 3.5" for some heavy duty punishment.
Ask for the SEALED uni's. They have no grease nipple and the bearings are sealed. Stronger due to no hollow centre cavity for grease and they're maintenance free.
You can go large 1350 size uni's, BUT, this all depends on the size of the yokes on both your gearbox and diff pinion. ie: there are certain uni sizes that can "step down" to your smaller yokes.
