I ordered a new fan clutch and 2 new engine mounts from USA Parts Supply for my 429. The guy told me they do not stock any engine mounts for a 429 anymore, so they sent me some to suit a 472. He said I will have to modify them to suit but it's not a big job. When I tried to install the clutch, it was way to big and hit hard up against the radiator, even with the radiator still pulled forward to give me some room. Then I installed the engine mounts...and they were identical to my old ones. No modification needed what so ever and bolted straight in. So seeing my interior was not an option for this car, could I possibly have a 472 fitted? The engine and body numbers are identical so I no it's the original motor from new.
