Hello

I have a runnig Glaspar 17 foot Sedan boat with a 65hp Mercury engine, and a Cox
trailer all is working.

However I'm looking for parts for the Cox trailer
which were at the web site www.boattrailerparts.com, but now the site is gone

I'm looking for 16 inches wide cradle or transom rollers?
(I found 12 inches, but no 16 inch.)

Does anyone know who the website belong to?
