leave poor mister 308 alone, i think most of this country was conceived within a few feet of one haha.
I used castlemaine mounts, they didnt fit. I should have sent them back back but i didn't, however, all i needed to do was weld another flange to them as the engine sat to far back hitting the fire wall. They were heaps expensive 400 and something dollaridoos. It was an expensive route to take in the end but it worked. If your handy with a welder and are willing to fiddle around try making them yourself. I can help out with the dimensions.
The gearbox i used was the det box, it fit fine but i needed to fiddle around with the mountings i think just swapping them over from r32 to 280(auto) something simple.
There is a z wrecker in adelaide (adelaide z cars) i spoke to one of them after i had done it as they had a 260 that they were dropping a rb25det into, bloke told me they bought 200zr sump, pick up and mounts from japan for 500 clams. he seemed pretty impressed with the price for some reason.
