I purchased this tool around a year back thinking I would use it to freshen/rebuild the Moser 12 bolt rear in my Z this spring.I have set more than a few gear sets up before so I know the processes involved and I usually go by the tooth pattern with marking compound to figure out pinion depth.Well I wanted to set this one up to Richmond specs exactly so I purchased the Proform tool hoping to make this a one shot deal.I always use the honed head bearing on the pinion so swapping shims is easy..but how the he** do I set this tool up?Does anyone have experience with it?I know there are better tools out there for this process..but I have this one and it is paid for..so I need to make it work.The instructions included leave alot to be desired...they suck.I have done searches on the board finding members mentioning the tool..but no one seems to mention set up or use??Proform seems to be of no help either..emailed there Tech and the sent me a PDF of the same instructions.Please help!!
