Problems fitting a RAM rear shock to a '87 K75C

[rbm]

I'm swapping rear shocks between my bikes -- a 88 K100RT and 87 K75C.  Went to fit the RAM rear shock to the K75C and discovered that the frame receptical is an eyelet pipe and not a pair of plates, as on the K100 frame.   The old shock has a fork upper mount and an eyelet lower mount.

The existing shock has mounts along these lines:



The RAM shock looks like this:



What are my options here for installing the RAM shock?  Will this require cutting out the existing eyelet pipe and welding on a pair of steel plates in place of the eyelet pipe?  It may or may not be important to know that I'm planning for an upgrade to a Paralever rear drive in the future, as that decision will require a 4V shock installation.

A RAM shock should bolt right up to any stock K frame.

Post up a picture of what the upper frame mount looks like on the bike that that first shock came from.

i have never seen a K with that mounting at the top.

Modded by PO, I`ll guess.

Ok, here are pictures of the shock mount.  What I'm expecting to see:

What is actually on my frame:

It does appear to be a mod by the PO; the work was high quality and it took me feeling for the grinding marks to discern the deception.  Obviously it was done to accomodate a shock that happened to be available rather than get the real shock.   :nono 

It means I will have to get a mechanic's shop to revert it back to the standard mount by welding on mounting plates.  :dunno

What I would guess have happened is that a PO have been driving around with a loose upper bolt for a longer time, and the holes have been elongated/out of shape.

Seems like you have some work ahead.

BTW. Your seat hinges needs to be lubricated, and you missing a clips.

That front E-clip isn't really necessary. (Unless you're using it to carry a spare. :yes)

[rbm]

Yes, I know.  That E-clip was on the bike yesterday because I put it there.  It wasn't there today because it fell off.  I did find it (miracously) on the garage floor this evening after taking the pictures and noticing the same thing myself.  You'd realize it is a miracle if you ever saw my garage floor.  :eek:
