Neil,
Look for some small radiator mounts. little rubber pucks with a threaded
stud poking out either side. I had the same problem as you on my conversion,
made some brackets that approximated the diesel one, but with radiator
mounts sandwiched in the middle. Look at a stock diesel setup and you should
get a good idea of what is required
