Oh i assure you I have read the article a few times... i am pretty sure i have the type L's on the front of my truck. I have made sure not to mix the rings up

I nabbed this picture from the guy with the rims,

he tells me that they have 20-7.5 tires on them, so they aren't exactly what i want.. but i think if i run some 20-7.0 around 35" tall tires on them the look will be close enough to what i want

also i snapped these pics awhile back of one of the rims off the back of my truck, its a BUDD brand rim and very heavy, much thicker metal than the other rims i weighed it in a 60 pounds

the tires were 8.5 wide and near 40" tall that came off of it, These rims appear to measure 5 in the center so would that mean you could run a 7" tire on it and i am wasting my time going to get the other set of rims?

I never would have guessed there were so many variances on these rims, i thought things were simple back then haha...

thanks again for all your help guys
