First a huge shoutout to AGLR4 who first mentioned shortening the crank pulley bolt and has been providing me guidance on how much he removed, from what end; etc....
As you can see I removed just shy of 1 1/4" inches from the right hand threaded portion of the bolt; this in essence removes the "nut" portion of the thread which is needed to help seat the bolt in to the crankshaft, I used the grinder to cut two new flat surfaces at approximately 10mm to match the factory flat surfaces. This was more than amble to get the bolt secured. I have a piece of cardboard installed to protect the radiator and will say that an overall length of 10" would be too long to get the bolt installed (how do I know!). With the modified bolt installed and secured in the crankshaft I was able to install the rest of the tool with ample room; likewise when the pulley came off there was room to remove everything. If you don't want to remove the radiator and you're willing to do a little fabrication this is a great workaround. Overall length is 9 13/16".
