I have mine bolted up using that front hole, but the rub goes around the frame and needs another securing bolt it seems because even when tight, it will just wobble side to side.

You can see the two bolt hole locations in the stock pic of the rub, and what mine looks like mounted.

Everything looks correct to me. I have a TM Designworks frame rub block and it doesn't have the second hole, only the one. If I recall, mine still rocked/twisted side-to-side some even when tight as well.

I misunderstood what you were saying about a second hole on the rub block but I get it now. Not sure what purpose it serves but its not an extra mounting hole, maybe its to limit debris from collecting under the block... I used a Moose rub block & it fit slightly loose like yours so I just filed down the collared washer until it fit snug.

They is a hook on the frame for the 2nd hole
That must be on the later frames because the 86 frames don't have anything on them for the lower hole. Thanks for pointing that out, I like learning all the little differences between the years. There's alot more than people realize. I wonder what year they added the lower mount for the rub block?

That’s interesting, I had no idea there was a difference either. I just checked the OEM parts diagrams - the part numbers for the 86/87 and 88/89 rub blocks are different.

Finally got the motor back in and buttoned up, fit the exhaust and just have to adjust some hangers and add some ultra copper to the joints. Don’t have much time to work on the project and some part fitments have been an issue but I guess she’s getting there. Once the pipe is done I’ll finish up the front end and get her to a roller at least.

Well after having all the issues lining up the rear caliper with the carrier I had, I received the LSR carrier and popped it in and the rotor hub sits flush in the carrier now so I was able to get the caliper rebuild done with new seals, pads and block off plate.

Got some time to get motor tightened up, new springs on and joints sealed up. Got the new shifter and sprockets on, and after power washing, degreasing and wet sanding the air box, got it back to black and shiny again.
Have to get a different rub block as I can’t get this one to stop wobbling side to side, if the chain touches it, it’s going to rip right off.
Front end will be done next I hope.
