Pat, Sounds like the old 65 must still be holding together for you. Good to hear that your "bargain" is working out. Had a chance to use my 75 this spring too. Still don't think I'd trade it for any shiny new 4WD, even if they paid me to-boot money.

If you look closely at the first pic, you'll see the tape-on steel pad that Trimble provided, in the front center of the cab roof. I originally had the antenna mounted there. I finally got the setup dialed in so it worked pretty good but it was no where near as good as the hood location. The suggested mounting location in the book is also the front of the hood. I intend to mount it on the hood of the 75 also.
