looking for anything to do with flatheads or 3 speed/overdrives,need to figure out what i've got.I've been told a 49-53 flatty,but the tranny been told 3speed/o.d "borg warner" don't know 6 or 12 volt or if it is a T85.on the passenger side of the tranny there is R10E-1 directly below it says W.G.DIV. On the driver sideon on the tail piece its stamp SB3 directly below A6-9. if anyone has anything its a start!!!!  

you would think their would be some site for helping identify motors by now
