19-inch Rear Wheel Conversion on XS1: Clearance Issues?

[patentgeek]

I'm contemplating a 19-inch rear wheel conversion on a '70 XS1 and am wondering if there are any swingarm clearance issues to consider? My plan would be to lace up a new, 19-inch Excel alloy rim to the stock hub.

It'll work fine in terms of diameter but you'll be limited to a 120 width tire max. See the last pic in "boardtracker-ish build" . 21" front 19" rear but on a longer swingarm due to shock mods. Standard arm will still work.
