I’ve ended up with a pair of Glencoyne mounts - which would need cutting to fit, and I’ve used those on the gearbox. They actually look like the V8 mounts
I’ve then also got a pair of smaller Bearmach round ones - like the petrol series ones, they do fit, and are as nice and soft as the Glenn Coyne ones.
Unfortunately in addition I’ve a range of other mounts - of assorted brands, that are rock hard that I bought before I ended up with the ones listed above.
Feels like a bit of a lottery.
