Spring ID - need an expert

Hoping one of the resident spring gurus can weigh in on this. While visiting my Powerstroke mechanic today he has a cut up F350 SRW that is believe to be a 2006 in his yard. The truck took major front-end damage and the frame was cut from behind the cab to part out axle and springs. No door-sticker, so trying to figure out what these springs are.

Of course I forgot to count how many leafs there were. But, there was a single helper and a small block between the leafs. Picture is of numbers on the bottomside of the pack. Axle was already removed. Any interpreters of these numbers?

After the 7C34, is that an F or ? Should have two letters there...

Or is it 7G34?

Either way, its a 2007 part.

If you can get me the last 8 digits of the vin I can tell. As RobRoss said, it should have another letter after the F.

Thanks Gents... Pretty sure it is a 7G34 F. What is after the "F" is of question. I'll have to go back and take a look at them. Won't be able to get the VIN # I don't think as the frame was cut behind the cab and the front portion of the truck is already gone.

From what I could tell from the limited info is that spring won't fit your Excursion, it's too long. I'll do some looking tho.

I agree that it looks like 7G34, however I cannot find anything on it. I do find 7C34, that spring is ~8' longer than what an Excursion would use. Rate varied over the suffix bumps (FA to FG) from ~324 to 348 lbs/in on the primary side, didn't look at anything else. My guess is that spring was on a 2008 truck. HTH
