Thanks gents for the comments.
JC, the l/h cover from a TnT can be used but needs to be modified for mounting hole position, trimmed top r/h to clear the frame at the top shock mount and a mount added on top of the cover to secure it to the frame....I found the correct one on ebay instead. R/h cover is MX2 which only neede minor mods to fit.
Still running standard style bearings.
I have fired it up and it sounds good but I haven't had it out yet - still have a couple of things to do and time has been conspiring against me.
