Does anyone have or know of an original crossram distributor splash shield?

Fits stock AMC heads, Traco was late to the game develping it for AMC for TransAm who then changed the rules back to a single 4-barrel, so the Traco AMC 2x4 Intake was shelved, unknown how few were produced, have info of two known pieces.  One was bought along with and on a used AMX in the 80's maybe not 10 miles from the Traco Culver City CA location, afaik.

Anyone know if the stock GM cross ram air cleaners have the same carb stud spacing as the carbs on an Edelbrock STR 10 manifold? 
I have the STR 10 on my 68 Z/28 and was looking at replacing the homemade air cleaner with one of the reproduction OEM style air cleaners (or an OEM one if I can find/afford one).
I looked through the thread, and didn't see a reference to this.  Only found the recommended air cleaner in the STR 11 instruction sheet. 
Did a search for that number (#EC-902P) and it came up with an air filter for an air purifier system :-)
I like the home made air cleaner, but it's sort of like that scene in the Apollo 11 movie where they have to build an air filtration system out of available parts on the capsule...
Thank you.



"we have to make this, fit into the hole of this..."


For reference, I measured 10 3/4 inches from center/center for the studs.

Gotta love the ingenuity.

Yes, it is certainly functional, and part of the history of the car.  I'll hold onto the homemade air cleaner, and keep it with the car.
I had one of the OEM crossram plenum air cleaners back in the 80's with my 68 Z/28 and would like to get one on this car someday.

Looks like the firewall opening may be challenging to retrofit an OEM style plenum duct. An easy hurdle to overcome.

It may take some correcting using this -
