Ha, I was actually in the same situation as you with a bunch of parts piling up in the garage until I had a trip to moab planned that forced me to actually install all the parts that I had accumulated. It was a mad rush over the span of like 2 weeks to get it all done even though I had it in my garage for like 6 months lol.
I am doing the same thing, every time I think about rescheduling the install I talk myself into holding out longer in order to accumulate more parts and just do it all at once lol. At this rate that might never end lol.
