"...I used the BMW flexdisc part to replace the revolvers. All I needed was a piece of 3/8 steel brakeline ($3.00) to make some bushing-spacers for all 12 of the bolts. The brakeline material fit snug in the disc bushings and the inside diam. was just right for the original Toyota bolts. I cut twelve about an inch long and used them as I reassembled the new parts. The six bolt hole diam. in the BMW part matched right up with the Toyota revolvers perfectly. The BMW flexdiscs were a little thicker than the original (1/16 to 1/8 inch) so after I had the shaft back in I just adjusted the three accessory carriage mounts forward about 1/4 inch. It went together pretty well. No more SADS rattle and no more vibration, it runs out smooth.:-) And this is the best part for me, it cost me about $80.00 in parts and five hours of my time on Friday afternoon, not $1200.00. I got the new BMW flex discs (for 1987 BMW 325i, with automatic, driveshaft flex discs) from
importparts.com, $37.00 each and free shipping, they came the next day. I don't know how they will hold up over the long run, but I have no reason to believe they won't hold up for many many miles. (the BMW part seems like a much heavier duty part) And I see no vibration increase on the accessory carriage. The whole van idles much smoother."
