WOW, those pictures were definitely worth a thousand words!

 

Ok, so I found a 1977 Ford Dana 60 that was just rebuilt with all new parts, 35 spline axles and a detroit locker for $1,500.00.

Is there a difference between the 1977 D60 and the 1978-91?

 

This answers my question...

And just to add, the 78-79 are not the same as the 86-91, the 92-97, or the 2000+

 

and $1500 is a rip off for a 77 LP 60

 

I went & looked at it this weekend. It is a HP D60. The seller also has a 14B with Detroit & disk brake conv for sale. I migh be able to get them both for a little over $2g.

The gears in the above two axles are 4.88's, my current set up is 4.10's w/35" tires. Truck is a 78 super cab long bed w/TMI 400, Howell Fuel Injection, ZF5 speed, NP205 w/twin stick, 3 link coil spring front.

RPM with 4.10's at 60MPH are 1850, with 4.88's at 60 rpm goes to 2190, still about 300rpm less than the 4speed. I'd like to get the highway rpms down some. If I stay with 35's I think the best gear ratio is 4.56.

I need some input on running the detroit in front. I've never ran auto locker in the front before. This is not a rock crawler truck, it's a DD, huntin' truck. I do quite a bit of predator hunting in the winter and sometimes the roads get pretty muddy and the highways are snow packed.

Question 1: Is the Detroit in front good or bad for my application?

Question 2: What are your thoughts on the gear ratio/rpm?

Question 3: Overall is this swap worth it in your opinion?

 

1- perfectly fine

2- perfectly fine for a toy, a little steep for a dd

3- yes
