I still have the top part of the spring top which was drilled. I lend this out if you pay shipping to and from.

Let us now if this helped you.

The 2 pieces for the compression is a 2 inch threaded collar. Found at any DIY store in the electrical. The top one I drilled it so the shock would fit and the cap would clear the collar.

I do lend this one out if needed. All I ask is you pay postage to and from.



You can see how little is drilled out. The threads are just barley left.

Bob just did this replacement. Here is his cost Jan 2019.

The costs were as follows. Rear shock springs (Progressive, kit D) $65.00 (includes shipping), rear shock seals (Honda, $31.95, with shipping) and, 1 QT. ATF @ $4.95. If my math is correct, the total comes to approx. $101.90!

The original (Amazon) link for the seals above appears to go to "Honda 91213-P2F-A01, Engine Camshaft Seal" not shock seals? Which ones are needed (could you include a link please)?

Thanks!

What exactly did you use to drill out the top collar, and to what size?

To what size?

The size is the top edge of the shock.

What exactly did you use to drill out the top collar--A drill press was used.

Well that bump stop cannot seem to find so I ordered the 98101 and it worked out fine with lil extra outta the middle like Wes said. My REAL question is, What did you do to replace the tower bushings? The last piece to my puzzle. Got em all back together but the rubber is not pretty and I still have time to get the right shock grommet. Any clue would be most helpful.
I used a ratcheting box end 9/16" on both sides cause I only had 1 thru socket and wasn't tuff at all.
And the parts have shot up a LOT more now. Springs are $99 and the seal kit is still reasonable and a few bucks for the bump stops. I also found a source for NEW Bottom Shock Boots if anyone is interested. I sure was...........google the GL1200 shock boots and you will find them too....


You can do anything, but not everything.
Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away. :ugeek:
