Jenkinsph,
I appreciate the compliment. I enjoyed the project and really enjoy using the machine now that it's done.
I got a decal kit from Tractor Parts, Inc. Here's a link:
820 Late Model John Deere Decal Kit. Now, the original yellow and black hood side emblems went from the front of the hood to the back of the hood but did not cover the side of the battery box just aft of the hood. For some reason, in this set, the hood decal is meant to cover the entire side of the tractor, including the battery box side. I thought that looked strange as I was used to the tractor with the shorter hood decal. So, I simply cut the decal of and overlapped the joint a bit so as not to get a grean line when things contracted with temperature and it really came out nice. I have a bit of a seam but it isn't noticable--much less so than if I had put the long decal on. Everything else was a 1-for-1 replacement. The kit had the shifter pattern decal, the PTO decal, the rockshaft decal, the air cleaner decal, and even some things I didn't need. I think the price was $65 plus shipping.
The 820 is a nice one to refurbish as it is not old enough to be a complete antique so you can still go to the John Deere place and buy most everything. Plus, it is old enough that there are a lot of really good aftermarket parts available for it as it was part of a very popular line with a lot of interchangeable parts. In fact, there are a lot of interchangeable parts between the 820, 830, 920, 930, 1020, 1520, and 2020. A lot of these were manufactured in Manheim Germany, including mine.
