ISO. Dana 60 coil spring 3:54

Helping out a friend with a ‘67 C20. His Eaton Eo52 is finished and he needs a replacement. Trying to get him a better gear for driving. Probably along shot, but would like to find a Dana 60 coil spring rear with 3:54 gears in good condition. If anyone reading this has one, please pm or email me at Lenox273@yahoo.com. Thank you. I’m in Northern Ky. If your too far away, shipping won’t be a problem for me if it won’t be for you.

Re: ISO. Dana 60 coil spring 3:54

Imho,
In 25 plus years of playing around with and owning these trucks I've only come across 1 Dana 60 C10- GMC1500 coil spring app. SPID code is G87, indicating a power lok rear. 1/2 ton Danas were used up to and including '70. 3/4 ton and 1 ton Danas are more common and we're used up to '72.
I'm currently doing a suburban build that came with this rear originally. With that said, it's been challenging to say the least because it's completely different from a 12 bolt GM rear that is more common and has a bunch of aftermarket support. Wheel choices, rear disc brakes, etc
Another consideration would be GM's 14 bolt semi float rear with 5 lug axles. This also is supported by the aftermarket.
A couple years ago there was a Dana 60 1/2 ton rear for sale on the board, not sure who bought it.
Maybe someone could find the link. Or if I find it, I'll post it.

Re: ISO. Dana 60 coil spring 3:54

These are out there in C20/GMC2500. I have a Dana 60 3.54 gear with Powerloc in a 72 C20 , but I am not planning on parting with it. Look for big block trucks with automatics, as most of the small blocks will have 4:10 gearing. When I bought my truck my initial plan was to convert the truck to 1/2 ton, but after some researching, I am leaving it as is and keeping the Dana. Good luck with your search.

Re: ISO. Dana 60 coil spring 3:54

Thanks Dave and Chevman. I’m am looking for a 3/4 ton 8 lug rear. My fault. I should have been a little more clear on that. Planning on doing the 14 bolt swap. Just thought I’d give a Dana search a shot before proceeding. Read a lot of archived posts on the swap and Dana option. Just trying to avoid doing a lot of work that isn’t necessary if I can run up on a Dana to start with. I’ll keep looking. Thanks for your replies.

Re: ISO. Dana 60 coil spring 3:54

We found one. It was for a leaf spring truck. But is a Dana 60 with 3.54 it came from a 70 fyi. The ring and pinon were stamped 10/69. So you may start a search with that info. Maybe older rather than newer. We had a Eaton 4.10. Swapped it out everything lined up perfect fit. May try ABQ c10 I think. Jeff is his name he has a rear from a coil spring truck. Dont know which rear he has. Eaton or Dana.

Not mine, and the wrong ratio, but pretty close to what you are looking for. https://www.facebook.com/marketplace...7983400569154/
