yet another exhaust manifold query

I talked to Sanderson last year about making a driver side shorty header for a 360 in a 64-66 A body.

They said bring in a car with all the stuff installed except the exhaust and they could build one for about $500.

So I asked if they would consider adding it to their line and what would the price be for a set (Their pass.side shorty and the new drivers side shorty).

They said if there was enough of a demand they would produce it and the price would be around $500 for the set.

What we need to do is take a poll for demand and a poll to split the cost of the prototype.

So is anyone in the S.F. Bay area with a 64-66 A body with a 318,340,360 , P/S , 904 col. shift or 833 floor shift, duel master cylinder, Mini starter willing to drop it off at Sanderson for the Prototyping.
