I hope this link works. If it does this is a day one picture of the Cobra 8V induction kit offered at a suggested retail price of $1,230.70 in 1963. There was even a Ford Motor Company "COBRA KIT" sales number for it.

This was the most complete installation kit ever offered and it was aimed at Cobra roadsters. As complete as the image is some small parts are not shown. By mid 1964 a very much less complete kit for $695.00 was offered (48 IDA/IDA1 carburetors) and installers had to figure out lots little details on their own. By 1965 the kits were down to $595.00.
With some variability in parts this is the type system with 48 IDM1/IDM5 carburetors was used until the 48 IDA/IDA1 carburetors reached the USA circa late March or early April 1964.
