@Roinik - Yep, that figures. Just looked in the 1800's engine bay (which AFAIK uses an Amazon front crossmember) and they definitely have a longer reach on the RH side than 140 mounts do. So the 140 / 1800 / Amazon powerplants will interchange, but not their mounting points, apparently.
The tradition appeared to carry on, too - B21 brackets use the same block mounting points as B230, but 7/9 engine brackets and mounts are totally different to 240. Lard knows why Mother Volvo did this, it's a completely different part that had to made and stocked to fit the same hardware in a different platform, and thus created a needless manufacturing expense.
I'll drop Josh an email about this issue with the 'vintage' engine mounts.
@dmc writes WRT the previous version of the engine swap mounts:
I was under the impression they used the 140/1800 engine mounts and made the B230 'look like' a B18/B20 so the original B18/B20 mounts just bolted up.
Ayup, and then one used offset 240 mounts to seat the engine. If memory serves, Josh revised the design not long after the TB thread Tim pointed to earlier.
About those brake booster mounts - yes please. I'll pick them up from you next time I'm on the mainland
