TTI Shorties in an Early-A?

Call Sanderson and ask for info on the model dd-9 header. I have seen them on a car before and the quality is very nice. I almost bought a set but I switched my 273 out for a 340 and got long tubes.
I have the Sanderson dd-9 headers for my 66. Not in yet, but mocked up look like the will fit no problem...Got thru summit....
