Geof,
I have a 93 Volvo WIA64TTES (Condo) with a Bull bumper. I'm new to this website. Here's the info that's on my sticker on the bumper:
ALI ARC
155 Elan Blvd
Winnipeg, Manitoba, Canada
(204) 253-6080 and they also have a web site:
www.aliarc.com
Hope this helps.
PS I'll soon post some pictures of my unit.
Donny
