Dad, Rim arrived. Largest that will likely fit all the way around. I checked it in the rear as its the tightest fit. Its a 15x6 rim for a 225/75R15 tire (same size as your 47 Chevy truck.) With that tire size, looks like our inside clearance between inflated tire and steel fender/inner fender well will be 1+" to fender and about 2" to inner fender well. Shes bright. I'll drop it off to get a Hankook Optimo or similar white wall mounted and balanced tomorrow. When its back I'll check fit again with weight on the rubber. If its good, will be ordering 3 more to shoe up Ol Bessy. Also, your third brake light will be red bullets on the license plate. Naturally, one broke on assembly so.......I have a do over to do but, they look pretty good. Since one broke I'll try to find some antique jeweled red glass lights instead of these LED models. But, assembled and wired here for proof of concept. Work to do in the woods tomorrow, rifle season starts Sat. Will be hunting the AM sat with Uncle Vic's WWII capture rifle. In between times I'll keep moving forward on the brakes. But at least today, I got new lug studs pulled into the axle and I have the axle brake lines and hoses now. So, moving quickly forward. Probably 2 to 4 full days work and then I think I must dung out the shop and start removing the front sheet metal. You see, we are rapidly approaching the need to purchase the engine, trans and cooling system.....Right on time/target. All is well. Don't quit your day job, its about to get expensive!
