OMC Specific Shimming Tools: Guage Lengths

Hello Gents!

I am in the process of rebuilding an OMC outdrive for the first time. I am in the process of tracking down all of the tools that I will need for the job. I have gotten pretty much everything but the special tools for shimming the Cobras are difficult to find. The part number for the shimming tool kit is 984329. I was able to find the frame which preloads the bearing assemblies so they can be measured but it was used and did not come with any of the gauge rods. Does anyone out there happen to know the lengths for the different gauge rods that would have come with the OMC Shim Kit? I can measure by some other means if I can simply figure out the lengths for these tools.

I have the 4.3L V6 (GM) Model 432APRGDP
My gear set is the 21:19

I am looking for the lengths of:
Short Rod "A" (for 21:19 gear set) U-Joint Shaft: ???
Long Rod "B" (for 21:19 gear set) U-Joint Shaft: ???
Drive Shaft Feeler Rod (part no. 328367): I believe this may be 8.273" can anyone confirm that?

Thanks in advance for any help or advice gentlemen!
