78 K-10 Measurement

[ARGluck]

I'm selling my 69 C-10 LWB and buying a 78 K-10 step side. The garage in my 150 year old house is unique at best and my current C-10 fits in it fine but I'd be lying if I said I had more than 6" of room from the nose to the garage door. The issue w/my garage is where the bed of my truck goes the roof drops quite a bit (I have to duck to walk in there) but it's 9' where the nose and cab sit.

My question is, do I have to worry about parking the 78 K-10 in there? I know they changed the wheel base some but how much of that translates to the front?

I guess if someone could just measure from the back of the cab to the nose of the bumper I'd be able to verify on my end. Thanks
