Correct, iv wanted one for years but she was a good price.
As for the diff iv learnt the mk3 zodiac or some mk3 zephyr crown wheel and pinion fit the transit square diffs and will give me a 3.5 ratio which should be better than the 5.6 that I believe I have. Failing that its just an axle on leaf springs so I’ll measure flange to flange and find a whole rear axle to fit.
These vans have the diff under the leaf springs so I’ll have to cut off the spring perches and flip them for the axle to go above to lower it more, at this point a whole axle out of something better might be the better option.
anyway maybe it’s time to start a build thread
