mistake in gears on scirocco.org site?

[raveracer77 at yahoo.ca (raveracer77)]

    In talking with Ron a few months back he informed me that the information for the AOP on most of my site references is wrong leading me to believe they all use the same source.  He told me that the Gear ratios may be right but the AOP had 90 mm hubs on them and not 100 mm like some of the other TD trannies I was looking for even the the gear ratios appeared to be the same.  My understanding is that the AOP was used in the 89 / 90 Jetta 1.9 NA Diesel, and the ACH was in an earlier Golf Turbo Diesel, but I've had to interpret the many different pieces of information I'm finding and many of them conflicting.  Now I'm looking for ATH ratios because they seem to be most consistent and have my 100mm hubs and the .75 fifth gear.  I'll let you know if my source for multiple cores comes through.  I'll post to the list before selling them to the local vendor.

  Ahh, gee, my perusal of ETKA yields a .745 5th gear for the ACH.
  The AOP has the same gear ratios as the ACH, but there are multiple 
  instances amongst all the 020 box codes that have identical ratio sets.
  AMC, CHE and DFQ being just one example.
