'88 swingarm length

[maryland450r]

Does anyone know what the length of a stock '88 swingarm is??? Center of bolt hole to center of carrier. Does 18 1/2" sound right?

I measure it right at 18

Thanks!
I came across a swing arm that looks to be a burgard stock length. I bought it for near future use. Everywhere you look to find length's of swingarms, all you get is -2, -1, +1, etc.
