I am looking for a tapered reamer.......   I have a pair of Granada spindles I am getting ready to install on the 54 Merc. for the disc. brake conversion.  I hear that the reamer needed to ream this lower support tapered hole is 1.5" inch per ft. taper.   In measuring my ball joint stud taper, with use of a conversion chart I found on the internet, I am coming up with 1.38"inch  taper per foot on this stud.  Has anyone reamed these spindles successfully, and still have the reamer that they used, and possably would sell, borrow, rent, or trade some y block part  for it?  I would think the 1.5" tapered reamer would work just fine.    1954 Mercury 312
