12HT into FJ75 ute project

Hi, well i only just joined this forum so a hello to all.
Ive just started my newest project (hopefully a little more usable than the last) of a 12HT into a FJ75 ute. I've wanted to do this conversion for a while as i reckon the 12HT will go bannanas in a 75 ute especially with a 3 inch mandrel and 10 or 12 psi up its ass.
I actually bought the engine before i bought the ute because its taken me ages to find a straight un butchered example of a ute 100% rust free and in my price range.(checked out over 30 utes) I got the 12HT off a family friend with a fully rebuilt bottom end for $5000 and the other day i was lucky enough to see a 89 FJ75 on ebay with a starting bid of $1500 with no pics so we drove the 80 or so kays from Caboolture where i live down to Ipswich to check it out.
This 75 looked a bit ruf from afar with it's beige paint but once we went through everything it seemed a real honest truck that had sat in a shed for 9 years (still had the 2001 rego sticker on it) totally rust free and straight with a buggered 3f engine. I offered him $2000 and he snapped it up. Wished it was a HJ but hey im not to worried and it actually has a few benifets. So now with the tray off and the 3f out and the cab stripped i finally have something to work with. First thing im doing is fitting the 12HT but first i have to cut out those petrol engine mounts and weld on a couple from a hj chassis, find some 2h parts and bung the whole lot together. Will keep you posted and look forward to any tips and ideas from anyone with experience doing said conversion. I am a diesel fitter so it should be pretty straight forward but hey i dont mind asking sometimes ;)

I think the mounts can be moved on the block, they have two different styles, and one of the styles should actually line up to the 3F mounts. I know its nearly bolt in for the 2f-3f conversion.

It should be easier than you think. Flip the pipe to the other side for your top radiator hose and it should hook up too.

Thanks for the info mate i will definatly check that out, havn't got my hopes up though. Yeah i was thinking about what your saying with the radiator but no sure weather it will affect the flow by just swapping top pipe to the drivers side??
anyone have any ideas on this??
thanks, Chris
