Most likely 4.10 or 4.56. Stock would have been 4.10 unless it is a camper special or ordered otherwise and then it would show the ratio in the glove box sheet. WES www.ClassicHeartbeat.com

It's a D44. I can almost make out the 44 casting in the pumpkin on one of your pics. Additionally, D60's do not use u-bolts but have studs to mount the spring.
Look on that little metal tag on that cover bolt. It should have the ratio.

4:09 would be correct. That means that you should have 4:10's in the rear. For some reason it is a design feature to have the front wheel(s) turning slighty slower than the rears.

Actually, the ratio is a function of the size of the ring and pinion, the case, and other paramters. You cannot get all ratios in all style housings because of those things. Later model trucks with 8.5" 10 bolts have 4.10 in the front, but the Dana works out to 4.09. What it boils down to is that the gear ratio is at least as close as the tire discrepancies height wise. In order to get any net pull of the front over the back like some mud runners do, you would need several percentage points difference. Like 3.90 in front and 4.10 in the rear. But don't do that on the street!

Thats a great looking truck ............ I am the process of restoring my 72 K20 and was hoping you could possibly post a picture of the emergency Brake cable hangers where it runs from the equalizer to the passenger side and then down the frame the owner before me has it run with plastic ties........thanks
