Thank you for your responses and suggestions, Georg at Valley Hybrids has rebuilt my transmission and transfer case and I'll be loading up my truck and driving back to Vancouver this weekend picking up a 3B from EBI in the way.
Fingers crossed it's an easy switch and I'm back on the road south...
I thanks for the replies, I'm at Valley Hybrids in Stockton CA, they have been extremely accommodating.
Unfortunately I have a broken crankshaft and replacement is difficult in the US. I might be back in Canada towing the truck soon.
