4G63 Crank Sprocket, Crank Bolt, and Washer General Dimensions

As time allows, I have been in the garage trying to complete a timing belt job. Knowing that reassembly is around the corner and without a helping hand, I decided that it was time I finally built a tool to keep the crankshaft from rotating while torqueing the crankshaft bolt. I kept stumbling around the site looking for dimensions to build my own tool to keep the crankshaft from rotating without any real luck other than general guidelines or "good'nough" dimensions. I was not able to find the answers to my specific questions:
1) What is the crankshaft sprocket bolt pattern? Ans: 40 x 40mm square
2) What is the OD of the crankshaft bolt washer? Ans: 40mm
3) What is the OD of the crankshaft sprocket "lip" around the washer? Ans: Approximately 44mm, but a little undersized at 1.729in [43.9mm]

I finally got to the point that the information, if it can be found anywhere on this site, is not easily enough found. I have the dumb parts, I obviously haven't reinstalled them yet - measure them! So here's the information in a nice, clean drawing for everyone. It is probably overkill for most but certainly a nice to have for those that don't want to spend the time with the tried and true grind-til-it-fits.

Dam I wished I had actually measured the tool I made. It is a piece of angle iron, with a half moon cut into it on one side with 2 holes to bolt right onto the crank sprocket.
I actually made the tool to hold the pinion on the GM 10 bolt Posi that my son and I installed a set of 3:73 gears into so I could put a load on the crush sleeve and decided it would also work on the 4g motors with 2 extra holes, so I drilled 2 more holes into it and it works great.
Was pretty simple, but I didn't write down any numbers, so I apologize. Looks like you finally did some math and CAD/CAM work. My crude drawing is just that, CRUDE.

Don't get me wrong, guys, I know about the different varieties of tools out there, for sale or otherwise described. I looked at VFAQ multiple times before deciding to create this. Gary, I will say that second link you provided I did happen to miss and, to be honest, still can't locate outside of the link you've provided (for some reason ). In any case, this thread was to provide the actual, critical dimensions of the crank sprocket, washer, and bolt - nothing more. Like I said, it's probably overkill for most people but since I was in it, might as well go all out!

Good stuff. I gave up long long ago and bought air tools. Boy I couldn't go back now. Hell just the ability to have air for cleaning and dusting yourself off is soooo nice.
