Mounting on a first gen Tacoma

Has anyone mounted their GFC on a first generation Tacoma? Mine is a 2002 with a 6 foot bed. It doesn’t have the bed rail mounts like newer tacomas do. What was your method to attach it?

I have one on my 1st gen. GFC provides 1st gen bed rail clamps, ask them.

Thanks! Would you be able to send me some photos of the top where it connects to the camper frame? Trying to determine if I could make something else work. Is yours connected with 4 of those?
