I'm looking to get my wheels ordered up. I'm going with 18" Boss 338s... my question is, 83' Elco with a stock rear. What would you recommend in the rear? I can get a 18x8 with 4.5" BS, or a 18x9.5 with a 5" BS. I'm not looking to slam her down but still need the tires to tuck in the rear. I already have plans to roll the lip so I am not worried there. Thanks
