bore of edelbrock throttle body adapter?

[SVT3183]

summit has it listed as 58mm (seems really small) and brothers has it as 70mm. anyone know for sure what it is? i would assume the 70 is correct.

My 94\95 Edelbrock elbow adapter was 70mm, the TFS is 75mm. 58 is the stock fox TB size, so I seriously doubt that is accurate for the Edebrock piece.

Yeah the Edel elbow is 70mm
