BLULMN

So boys have a ba manual Ute welded my diff a couple of weeks ago for some extra fun and I keep snapping the bolt that holds the leafs together, has anyone had this problem and found a real solution?? I’ve tried putting high tensile m8 bolts in but because the head of the bolts are so short the diff doesn’t have a comfy place to sit so the diff just slides back and forth. I’ve also tried putting a couple of nuts either sids of the leaf to stack it up a bit but I just bent and snapped them in seconds. Thanks

What’s needed to change rocker cover on an na ba to the fg one? I’m told I’ll have to change either coils to fg ones or use something to keep the coils down from poping off while under load with the stock ba/bf coils and I’ll need to change the manifold? Thanks in advance
