Thought it'd be useful to put some information and a few pics of how I did my solid mounts as a few people have asked recently
Mine was done with a bare block/gearbox for mock up, Chris Astley front mount (same as all the others) and TAS solid mounts.
Rear mount slotted
Front mount on the middle hole
Front mount on the top hole
Modified bracket
And how it sits in the new hole
After these modifications, it's important to strengthen the mounts again... Front:
Rear:
