I just ordered two .28 RRs myself, yes two. I dusted off my dual engine shelf queen and am now putting X-easy access gear on it as well as the 3spd guts into the gear box. I intend to mount the RRs into it, but due to CB clearance problems, I have to modify the TVPs so I can mount 20T CBs and mate that to a 47T steel spur. I am going to take pics of my twin engine carcass right now (I totally disassembled it) and post a pic with a couple of K4.6s in it. It is only the TVPs, the engines, and the X-tranny case for now, but I will post a pic of the twin .28 RRs in it when they come in next week. Please forgive the poor picture quality, I have a cheap-o $20 target camera.
