Maybe the mice carried them off for their own car?Why have wing bolts disappeared from Monty?
I left a small pile of them on a chassis leg (when the car was on the roller) and forgot to bag them before putting the car down and back up again. - I never found all of them.
The head snapped of one (i got the rest out of the captive nut though ) and another couple were pretty rusted.
I also never found the missing rear spring shackle plate, a small screwdriver and a few other things. Now I think of it, the mice MUST be doing their own resto job - can't wait until I find out where they've hidden their car (it could be in the garage behind all my junk) ;)
