Disc dimensions

[JimnhR]

What are the original center-to-center bolt hole dimensions supposed to be on the AR1052R double facing clutch discs that fit an R?

Yes, I'm not sure why that that comes up that way on JDPARTS.COM unless perhaps JD reused that part# years later but RE29785 is a disc for a JD 4000 series "Compact Utility Tractor". The AR1052R I need dimensions for is for the 2 Cylinder Model "R" tractor shown as item# 22 in the PC0183 JD "R" parts manual. That 2 cyl disc subs to AR403R which unfortunately also comes up on JDPARTS.COM as the RE29785 for the same "compact Utility Tractor". Does anyone know the dimensions I need for the "R" AR1052R disc?
Thanks
