How large of wheels can i fit 2wd
 

Hey guys! Hoping for a bit of advice. I am midway through my 2wd conversion on my 70 Blazer and I need to figure out my wheels. The rear will be a 79 c10 truck rearend, 4 linked, notched, and will be tubbing the floor. Trying to figure out how wide i'll be able to fit back there? It will be airbagged and very low. Hoping to run maybe the US Mag Rambler 22x11, but if that's too wide I will stick with the 20x9.5. Thanks for any advice!!
