I know people are strapping these to roll bars but I need to see how its done. any pics would be helpful thanks. I have mine strapped back there but its always coming loose because it doesn't sit up flush to any thing.

 

Anybody ????

 

I would just weld 2 wheel studs to the bar, the appropriate distance apart, and bolt the spare on with lug nuts.

You could also drill through the bar and weld a 3/4 " over the hole. Then buy a foot long 3/4" bolt to thread into that nut through the hub-hole of the rim and weld some flat bar to the bolt head that will screw tight against the tire... like how a trunk-floor mounted spare system works but horizontal.

It's probably not a very famous idea though, have you taken an entire load of passengers camping in a 1st gen AND carried all the crap? Space is limited and entertaining a large spare you may or may not use is not a welcoming option.

Not to knock your idea... that's where mine was at one point, but space is limited and you'll find out quick.

 

ratchet strap through the wheel tighten it up mine has been like that for years .

I check the air pressure in place

 

I have mine back there with a ratchet strap now, but I would like to see how people are running the strap, because the tire does not sit flush to the bar it keeps loosening up.
