I've read the archives and find a lot of info for 65-68, but not a lot on 69's. Would like to hear some first hand experiences on 69/70 tire sizes, back-spacing ect. It's my brothers car, and he's not really into the low profile tire look, so we're limited to 15" tire sizes. Paint will need touched up, so rolling fender lips is an option. He'd like to go with 8" wheels all the way around. Any experience or advice you wish to offer would be appreciated. He's leaning toward Magnums or Tourque Thrust D's, but everything is up in the air. BTW, it's a gulf stream aqua 69 s-code. Thanks.
