Like Ted says, RAM mounts save the day....for us anyway. We've used RAM to mount the Insight into a couple of different JD 9xxx combines. We RAM'd the Insight into JD 8420/8430

Hagie sprayer is Ram'd. Buhler tractors are Ram'd.

I'd sure like to find a cheaper place to buy the Ram Mounts. If anyone knows, I'm always interested. I use GPS City:

Good luck w/your installations. I'd sure always 1st consider a RAM mount

Here's how I mount the  RAM ball to the Insight (below):

Here's our RAM mount off a JD 8420 corner post. That slide bracket you see in the side window is from Shoup. We modified it slightly (below).

Here's driver's view of 8420 (now 8430) w/RAM'd Insight & other stuff. PS-JD supplied/mfg air compressor now resides outside. (below):
