So managed to do a bit of metal cutting, drilling and tapping last night. Fets mounted on a piece of 90mm x 160mm x 10mm aluminium plate bolted to the case floor and a piece of 2mm aluminium angle bolted to the MURs and a piece of the 10mm plate bolted to the angle.
The mod to the rectifier has worked nicely and they are now just warm to the touch.
However, the Fets seem to be hotter and the aluminium plate is very hot. I am going to use some of the angle and a piece of the plate bolted to the bottom plate and the side of the case to the right of the photo to try and spread a bit of the thermal load.
