    '72 ST Velocity Stacks

    Question / request for the forum - I've seen sets of fibreglass velocity stacks / intake trumpets on a couple restored original '72 ST's (photo below) they seem to be used when the engine has flat slide throttle bodies - does anyone know what they are, who they were made by and, fingers crossed, if anyone has some that i could either buy or make a former from to recreate? Thanks - Charles

    Thanks Oliver, that’s certainly the right material albeit, as you say without the top injectors. Alas no luck from
    the other suggestions so far as all seem to be plastic moulded and shorter. Still happy to hear any help for the experts out there.
    Here is one car with these stacks…
