Way of identifying year of a front suspension?
I bought a complete front 5 lug suspension from a local a few months ago, and the day of bolting it into my truck is approaching. I can't remember what year the guy said it came from. It was bolted into a 60-66 when I first looked at it, so I know it will bolt up. Is there any obvious differences between 71-72 front end, from a 73-87 front end? I looked through the 2B section of the FAQ's, and didn't find it.
Cheers! |

Re: Way of identifying year of a front suspension?
Ok, great! Thanks for the quick reply! I may be just suffering from over information overload, but a later 5 lug rear axle isn't plug and play, correct? I believe I read that they are a little too long. Isn't the most cost effective way of going 5 lug in the back buying the 5 lug axle kit from somewhere like Speedway? If so, I will probably just buy a set of the after market 6 lug front rotors when I rebuild the front end. Sorry about beating a dead horse, as I swear I have read this before...

Re: Way of identifying year of a front suspension?
The '71-'87 differentials are 1.5" wider than your current differential. A '71-'72 12 bolt would be a direct bolt in into a ''65-'70 C10. A '63-'64 will require some fab work or modification to the panhard bar. A '73-'87 differential will need the original spring pads and shock mounts removed and trailing arm mounts and a panhard bar mount welded to it, at the correct pinion angle.

Re: Way of identifying year of a front suspension?
If youre talking about just swapping axle shafts theres a width difference. If you want to swap the whole axle it takes some cutting and grinding And welding (Less if its a leaf spring truck but still some light fabrication. So yes. In the long run a 5 lug axle shaft kit and new drums is less expensive than making the later model stuff work. Especially if you dont like grinding and welding as the shock mount and bump snubbers on the later trucks are an odd arrangement.

Re: Way of identifying year of a front suspension?
I have 75 front suspension with a 72 rear end. I got lucky finding the 72 rear ends on craigslist and at pick and pull. The one in the truck now I picked up for $150 and it is tight and the one I got at pick and pull needs to be rebuilt. Here is a picture so you can see how much the rearend effects anything. I think I have a 4" back space on the wheels that are 7" wide, the tires are 245/60/15's. Thinking of getting 17" wheels next.
