I am starting to work on the rear cross member and also the final "set-up" of the rear spring for the speedster project. From what little I have researched there was a 6 leaf, 8 leaf, and 9 leaf version of the rear spring. The 9 leaf being for the sedans. The six leaf for roadsters for a short time, and the 8 leaf being more common. I think I would like to have a 6 leaf version for the speedster. But it appears to have not been used for long. and the 8 leaf seems to be the most common. So what is the differences between the different leaf combinations. Are there "special" lengths for each combination or can I just remove a leaf or two from the 8 leaf set. I am not changing the front spring any. But the rear does seem a little stiff with 8 leaves. I have several sets of rear springs and lots of "single" leaves but I would kinda like to know what Im looking for before I start dragging all the heavy things out. I also have a 2 inch dropped rear cross member. So more lowering with the springs is not really needed. Thanks .... Donnie Brown .......

Check the parts books. As I recall, the 6 leaf spring was only used for a short while, and is unique unto itself.

I looked at my 6 leaf spring today and the first leaf (main leaf) and the second look to be the same as the 8 leaf spring. The third leaf has hole in it for the spring clamp and is a different length and so are the other leafs. The 8 leaf spring has a hole in the fifth leaf for the spring clamp.
If you want the spring to be authentic you will have to find the real 6 leaf spring.
When you are looking through your pile of springs look for one that has the spring clamp close to the end where the spring hanger hole is. The 6 leaf spring clamp is three leafs from the end and the more common 8 leaf spring clamp is on the fifth leaf in. That is the easy way to tell they are different.

I have been restoring T,s for a long time I have never seen a set of rear springs with only 6 springs . The early roadsters had 7 springs like my 11 Torpedo should have on it . Unless you are not counting the large first spring that the shackles go through . Last year at Chickasha Royce Peterson had a set of Torpedo springs , He and I lay them on top of a set of 8 or maybe 9 leaf springs . The shape was not even close , the 7 leaf springs had much less of a hump in the spring .
