Hope this helps somewhat - the drier is in fact a horizontal unit with inlet/outlet on the ends, so if you have all the factory lines/hoses, you'll need that style drier. I'm not aware of any new or reproductions of them. Good news though - if you have one, that AC place down in Tampa will rebuild them for I think $90 or 95. I sent 2 to them and they're now sitting on the shelf (capped of course) waiting for me to get to that point. The drier lies about midway on the horizontal part of the inner fender. The water valve is to the rear of the drier. There might be dimples in the sheet metal for the appropriate mounting locations - there is on my 65 'vert. After I get back from helping my youngest son with some plumbing, I'll position all the components in the empty engine compartment of my 65 GT 'vert for pictures
I "think" I might have an extra, crappy looking early A drier - I'll have to dig around and check. IIRC it might have come off a 66 Barracuda and was rusty and pitted.
