I'm working on rebuilding a bike I bought for my grandson. I thought it was an original Stingray until I determined the frame serial number is for a 20" 62 Typhoon/American bike that was converted to look like a Stingray. Everything else is original including the rims and tires. My question is can I replace the rims (S7,S2) with non-schwinn aftermarket ones so I can replace the tires with 1.75 size tires which are easier to find and cheaper too. Keep in mind, I'm not trying to restore to original Stingray condition. Thanks,
