I have the R3000 recip saw. The blade release lever is missing. I am wondering if the release lever from the R3000s will fit on the R3000. The release lever is sold individually for the R3000s for $1.46, but for the R3000 it is only available with the purchase of the gear case assembly for $33.75 plus shipping. The saw is not under warranty. Any advise helps. Cheers.
