I took an old long engine mount bolt that was 10 X 1.25 to begin with. Most bolts like this have more un-threaded shank than threads. Then got a 10 X 1.25 die and turned new threads, enough to allow the bolt to thread to the bottoming spot, then install & zap with a 1/2" impact.

I think this bolt was from a CB750F, seems Honda likes really long 10MM bolts for multi-cylinder bikes.

Here's an eBay ad with a photo of the 750F bolt.

Here's what I ended up doing. Got two 10-1.25x50mm bolts (the longest fully threaded I could find locally). Cut off the head of one bolt, cut it down to 1.5", and ground off the thread. Slid the cut one into the armature first and then used the bolt with threads to turn the armature out. Looking back, I could have saved myself some time and just got a smooth metal dowel so slide in there... live and learn. Thanks again for the pointers.

Glad you got it. I thought of the dowel but it is probably hard to find and in 36" lengths minimum. When searching for all thread rod the prices were running in the 70.00 dollar range plus shipping. Good idea Apex.
