Hi bcuster. Sorry for the delay.I actually went out to my buddys yesterday and installed the toolbox on a cabbed B2650. It fits like a glove and ends up being 2" away from the cab and the exact same width as the cab so looks great. It looks like I designed it for a cabbed model. Got lucky there. The only issue is the latch I have for the non cabbed model hits the cab when you go to open it. I am going to come up with a different latch for cabbed models as I have several people with cabs that want one including one that wants one for each side of his B2650. It takes seven hrs with cutting all of the pieces out of 1/8" steel, welding it all together, priming and painting. With all of the shop time and materials the toolbox is $150.00 plus shipping. Any other questions let me know. Thanks Ron.
