specifically on a 1971 E body?

Are you looking for the parts counter p/n or the number stamped on the springs?

These are the factory over the counter part numbers.

here are the numbers that are on the springs themselves

E-BODY
LEFT SIDE, 6 LEAVES (LOWEST LEAF IS SHORT) #3400034
RIGHT SIDE, 5 FULL + 1 1/2 LEAF 3400024

68-69 B-BODY
68-69 LEFT 2539795 6 LEAVES
68-69 RIGHT 2539965 5 FULL + 2 HALF LEAVES

1970 B-BODY LEAF SPRINGS 2539794 2539964

Thanks,

Although I need the numbers on the springs themselves. I'm looking for the numbers on a set of springs that may have came on a 318 powered car.

In FAST the 440/Hemi springs are useless. If you want the car to hook up you need the junk 6cyl/318 weak springs.

Thanks for posting.. Anybody have the numbers for the standard leaf springs?

Actually I need to know what this number is for? 3400014
Picked them up but the guy didn't know what they came off of?

If anyone is interested


3400014 - L&R '70 e-body 318/383 2bbl
3400015 - L&R '70 e-body convertible 318/383 2bbl

2539534
2539794 - LH 6-leaf '68-'70 b-body w/440&HEMI (some not all) and '71 b-body w/DANA (or some w/G60-15s not all)
2539964 - RH 7-leaf '68-'70 b-body w/440&HEMI (some not all) and '71 b-body w/DANA (or some w/G60-15s not all) 

the last three digits are on a b'cast sheet
1970
/6 - 013
318 - 014 = #3400014
1971
/6 - ?
318 - 344

I did some research and this is what I have observed.

A lot of Broadcast Sheets have the wrong torsion bar and rear spring part numbers. For example: 318 cars with hemi suspension, 383-2 cars with slant 6 suspension, etc. The system operator probably forgot to change the information from previous cars(?)

Thanks

I have been looking at this list and have to wonder if the convertibles have a slightly stiffer spring rate more so than a coupe. The wheel housing is actually more shallow at the top due to the convertible top clearance needed. So logically you would think the spring rate would try to counter the wheel from getting even close to bottoming out up at the top of the wheel house. Plus, I would think a convertible is slightly heavier that a coupe?

I had to get my opinion out there. What the real difference is between a convertible spring and the hardtop, I would love to know (except for the explanation Detroit spring said, its a bushing not installed in one vs the other). There is a consistent part number difference between them.

I just pulled 024/034's out of an original 383-4, 4-speed car.
Car came with 15x7's.

any '70 340/383 B & E-body with an axle package A31 (3.91s) or A36 (3.55s) will have the STANDARD in 440/HEMI torsion bars 780/781 & rear springs 024/034.

it could be something they learned in 1970 as the similarly equipped '71 340 convertibles have 3400045 springs
