I put a 3 point conversion on my Series 3.  The top link mount is my question.  The lower/back part of the mount has holes large enough to fit over the studs/nuts for the PTO shield.  The shield has to come off due to the stamped strength ridges being in the way, which just leaves the (now useless) short 3/8 studs.  Thinking this needs to be bolted here (correct?), I took out the studs to be replaced with longer bolts (I did not have 2" studs).  Oil comes out the empty holes (through drilled into the diff), so I used sealant on the new bolts and put the shield back on top of the mount.  No leaks yet.  I now have studs.  Should I put them in or wait to see if / how bad, it leaks?

DOn't just use those PTO bolts for the top link bracket. That's not much strength to hold a heavy load. Get a bracket that bolts to the 3-point and under the seat.

Bolts will always leak there.  Studs thread in much tigther - they don't leak.  Just get a couple of longer studs to compensate for the top link mount.  Get a good mounting that goes under the seat suspension.

I got this kit from OK Tractor, so the the top link bracket they sent DOES go under the seat and bolts down with (new, longer) 1/2" bolts.  I'll pull out the 3/8" bolts and use the 2" studs, with sealant.  Thanks.  I did/could not use the "anti sway" bracket, since it would not fit over the drawbar bracket,  which seems to locate the arms pretty well.

OK's looks a bit different, but it's in and seems like it'll work just fine, after I swap in the back/lower studs.

Thanks.
