Original 40's on 83
I have settled on Flow master Original 40's for my 83 SWB. Current set up is Dual exiting out the rear. The pick up does have the original dual gas tanks and a th700r transmission. Is there anything I should be aware of as far as the fit or any modifications that I may need to do to make them fit? Thanks for everyone's insight! ! Ryan
