finally got around to fitting my simple 2" block today, per the Brazilian guy's design.
unfortunately my drive slopes, and after disconnecting the stock bolts, the diff rotated against the propshaft. I was expecting and had prepared for this and so had to chock the car and jack up the chassis to get room to insert the block, then jack the diff input collar (with a wooden block!) to get the right angle again.
all went together fine, 10mmx8.8 bolts, 3|removethispart|@ 80mm & 1 |removethispart|@ 70mm.
not easy to tighten up, so I'll check it again on the level after a few miles
what else do I need to adjust now? brakes?
