Chassis headers vs Fenderwell headers

Not sure of the name brand either, they have been laying around for ages, could be Lemmons? Sthall? no name on em anywhere. Already have the Cheetah shifter, for a powerglide the cable does come in from the rear, on the 727 it comes in from the front which would work, not throwing the chassis ones in the scrap pile just yet. All of the bracket racing stuff in this pic is gone, delay box, TS timer, transbrake buttons etc etc. The street beast is coming along, slowly but surely.
