8mm long for backplate, 12mm for head, and I think the muffler needs 18mm length, all 3m diameter x .5 pitch. You can probably get all these from the R/C car section at the LHS, or a good Ace Hardware store.  H^^ Steve

Would backplate from a LA46 fit the LA40?

        Jamie, you can probably find them at Hobby Towne, Baton Rouge. I converted some OS's and got some off their Sig/Dubro rack, but most I got from R/C car/heli dept his sons handle. They keep a lot of metric screw stuff.
