Is that the Mountain Man shaft?I remember it using a cv style joint at the back.
I dont think it's a Mountain Man ? The end that bolts to the rear end looks like Mountain Man,I had one that I gave to that JackAss a few months ago & it did not look like that, mine was out of a 08 GL1800 CSC. I have a 89 GL1500 Lehman I looked at that & no part of it looks likes his ? The yoke must still be stuck in the back of motor ? Pull that out & maybe you could put a U-Joint in it ?
