my son talked me into dragging the trans out of the corner the other day. i am not sure how i came to own it. i either got it with the flathead i bought for the mh years ago, i think it came out of a f1 monkey face, or i got it with the 52 f3 mh when i drug all three loads of that truck home. it just dawned on me i should go lay under the f3 and see if the trans are the same, but i have typed this far so im just gonna push the submit button. thanks all
