Looking for a set of the extensions. Found a set years ago now need one more set.

They bolt to the ends of the 876A and 877A rock shaft arms giving a 6" longer reach.

There are no extensions for the rockshaft arms shown in the parts catalog, PC-397.
How hard would it be to make another set like the one you already have?
 
The only use for extensions that I can think of is a front mounted, cable lift snow plow. The extensions get the cables under the rear axles so they don't "saw" on the axles.

Some of the 2-cyl snow plows use cultivator lift arms and need extensions that are shown in the plow catalog, PC-228. These extensions are just a piece of flat bar with holes drilled in them.
 
Are you talking about Part # 8145-c extensions , Used with JD, No.20 rear mount scoop, when used on No. 800 hitch; (I think that was only Imp. JD made them for) to get higher lift, ground clearance.. see pic. Check JD parts , PC-314

I looked at PC-314. Looks to me like those extensions go on the bottom end of the lift links, not the rockshaft arms. Rather than give higher clearance, they get the pan deeper in the dirt.
 
The set of extensions I already have bolt to the ends of the rockshafts. With rebuilt PowerTrol and bypass pressure factory set the 60 has no problems at all lifting my 812 plows out of a cut.

These extensions also look factory made and your right cannot find them in parts catalogs. A few years ago the set I have quite sure I found them off EBay.
