1983? Likely. Check the Sugino crank for date codes.

I would have just assumed Panasonic, like it was in the mid-70's.
For the record:

Schwinn Le Tour models, of the various designations, with frames made in Japan where made by at least three different manufacturers: Bridgestone, Panasonic, and Kuwahara. Each frame manufacturer has their own serial number formats.

Edit: The OPs frame serial number, as mentioned previously, is a USA serial number.

This post doesn't seem be online any longer. I posted some photos but, after that my thread disappeared. I discovered that the BB didn't need to be changed. I used 6 mm spacers. I noticed on my 30T ring that it was recessed on one side and, the gap was almost perfect. I had to reset the cable 3 times due to stretching. But, I finally got it. The one issue I did have problems with was shifting to the large cog on the freewheel when the front chainring was on the 52T. The chain kept pulling off but, I think I got it finally. I went to the bike shop in my area and, showed the mechanic what I was doing and, he said "those derailleures are ancient" lol!!! Thanks Hudson!!!

Good job getting it all to work!
It's great that you got the chain to work on the big/big. Experienced riders will tell you that may not be completely necessary, as that's not a cross-chain combo they would use anyway. However it's always nice when you can get any possible gear combo to function.

As far as the BB spindle length, I would assume you'll need a longer one. I never measured the length when I had it apart.
One thing about this particular BB is that it's an easy swap going from a double to a triple. There's enough clearance. Just be mindful of the spacers you use. I used 6mm spacers on the small chainring and, I was able to use the friction shifter that came with it. At first the cable kept stretching while I was adjusting the H&L but, after about 4 tries it finally held.

GC is '87 but it's really not likely that an '87 bike had top mounted shifters. They were almost always found on 83-84 frames. Your bike looks to be in this 83 catalogue. Arx derailleurs, same crank, correct shifters?

I think maybe the date code is elsewhere on the crankset. Reading thru the thread, this was all covered already.

I'll keep looking. I definitely like the 83 water slides better than th 84s.
