Curt,the outlets are the same bore but different spread on the studs.I am unsure if this applys to the repo Fentons but the originals are set up to take a donut one the foward header,on the back header it takes a flat gasket.When these were designed,the cars were new and they only added a 2nd pipe/muffler unlike now where we run complete new exhaust systems.
On the side cover,will it be cast or machined?There was already a small run of 15 made recently off the original pattern/mold.I talked with the guy that has the pattern and he said he would do another run if there is enough interest.I am trying to spear head this to get it done.
The linkage looks great but we need more pics and details,your not getting off that easy.
