Thanks fellas, much appreciated!
Swarfy - it's a '61 Flash. Not too concerned about the proximity of the chain to the inner primary, seems to be plenty of room even with the plate (which is present). The rear fixing of the inner primary to frame is pretty good (only one washer

), but I like Col's suggestion of putting the primary cover on first and tightening everything up before securing the rear fixing. This would seem to take any strain/flex off the inner primary allowing the two surfaces to mate better. Also, is there any sense in putting two gaskets on, seem to have an issue with primary leaks?
Julian - thanks, I'll look into that one.
Bergs - the nut wasn't great anyway. I've not really damaged it too much but I think it's time for a replacement anyway. Not sure how the cush nut would bottom out mate, doesn't it just screw up until it hits the collar sleeve?
Col - did you have any issues with bottoming out?
Musky - cheers mate, will check them out - would be nice to keep it as original as possible.
Anyone want to comment on how RM missed this alignment issue - being a specialist in classic rebuilts, of course??
