Sorry, don’t have a picture…Post some pictures or email them to me so we can see what you are dealing with…
The only other thing I will add is that you should not use the 1975 driveshaft (with oring groove) on the newer engine with the two seal system on the powerhead. Even with the oring removed the driveshaft, the oring groove might line up with the bottom seal rendering this system useless. The other problem is that the oring groove might grab the seal lip (while removing the gearcase) and ruin the seal.
