OHV TPS bolt size?

[ajr2000]

Anyone know what size bolt is used for attaching the throttle position sensor to the throttle body on an OHV. I put on the BBK throttle body this morning and stripped the head on one of the screws taking the TPS off so I'm only running one of the TPS screws now.

For 6 bucks, at the Ford dealership here, I got a set of four of those (they only come in sets of four). I just picked them up yesterday. I had to drill out one of the old ones.
