Re: rear coils
I have a 66 longbed fleet parts truck. The springs are original and I'll post pics when I get home. The rear springs look a bit stronger that the rear springs on my 65 short stepside. I'll count the number of coils too. More later.

Re: rear coils
OK, so here are some pics of rear coil springs that have not been cut (or heated up). If you compare the coils of the 65 springs with the 66, the 65 coils seem spaced further apart. The reason for that is unknown to me. I do know that the 66 longbed was a truck that hauled fruit, so maybe it was loaded down a lot of the time and the springs sag now. Or maybe it's because the 66 still has a cab and engine on the frame and the 65 has nothing on the frame. The last pic has the cab and the engine on the frame but no bed. I count 7 complete coils.
This is the 1965 rear spring with the bed off and the cab and engine still on the frame - not much difference.

However, I am calling attention to the fact that my 66 rear innermost coils (#3,4, and 5) are spaced closer together than the same innermost coils on my 65. I think it's because they lived a harder life than the 65 springs. I agree that the general shape is still the same. I can fit my finger between the innermost coils on my 65 but not my 66.

Re: rear coils
Sorry to hijack but in the last pic it shows the bottom bolt coming up thru the trailing arm and into the welded nut on the spring cup. I just put new cups and springs on my truck and wasn't sure if I had it right. I have the bolt going down thru the trailing armto a nut and washer on the bottom of the arm. I used the cup with the welded nut on the top mount of the spring. Do I have it backwards or do you or does it matter?

Re: rear coils
Thanx! Looks like I have the cups on wrong. I'll have to switch them around before I put the rear end back in.

Re: rear coils
1966FLEETSIDE, based on the number of coils and the fact that they have a 'pigtail' on each end, I'm thinking you either already have drop springs or perhaps jeep springs. I'm on the hunt for jeep springs now so I can't tell you for sure because I don't have them in my hand. Good luck and let us know what you decide/find out.

Re: rear coils
Do original coils weaken or drop height over time?

Re: rear coils
Yes they will. Depending on how overworked they were will depend on how much over time they will sag. This is why it is very hard to figure out how much to drop any old vehicle as if the stock springs sagged enough, putting "dropped springs" could actually raise the vehicle higher than were it was.

Re: rear coils
Here's a pic of the stock springs from my 63 SWB they measure 13 in unloaded. I'm sure they are wore out. I bet they are an inch taller new. the second pic are the Jeep TJ ser. springs I put in for gbrowns info. dropped the rear 3.5 in. So I'm callen it a 4 inch drop from stock.

That's what I think is my issue. If I let all the air out of my air shocks, the rear tires rub the rear step fenders. But if I put enough air in the air shocks to keep the rear high enough to not rub, the ride is pretty stiff. I do have air bags that I plan on going with in a future upgrade. I'll resolve my ride height issue then.
