Wheeeels

[ShinyC10]

So I pulled the trigger on the stage 1 air ride kit from AZproperformance for the 73-87 model truck. Front consists of the plates/cup with the bags with the stock control arms and the back is a bolt in 4link from ridetech. I got some Vannatta front inner fenders coming in in a few weeks. I got my eyes on some wheels (us mags boulevard 20x9.5 and 20x8). Curious if the back spacing is going to be an issue with these. 20x8s come with a 4.54bs and the 20x9.5 with a 5.29bs. Back has stock tubs and bed floor. Any help is appreciated, thanks 👍🏻
