My small garage

I should be thankful for my small garage. Seems that I spend more time looking for parts than I do working on my 65 Formula S. I'm in the process of rebuilding my 273 Commando. I have new pistons installed. The new oil pump is installed. Heads are ready to install.
So I installed the oil pump but can't locate the oil pump shaft. I know I can order a new one, but know the old one is there. I had everything together but had some help in the garage cleaning up last weekend.
Do any of you have issues like this or is it just me.
