Throttle Body update?

[Darkwaters]

Hello, I have an 01 Sport Trac. The assembly date is June of 00, my problem would be I purchased a power aid Throttle Body spacer to go along with a Cold Air kit, it seems Ford changed the throttle body six months into production of the ST and though I've tried a couple different spacers it seems nobody makes one for a six month production run. Can I swap out the throttle body itself from the later run?

Aluminum and Plastic throttle bodies are not interchangeable.
