roadster rear spring

[dave in australia]

I am restoring the rear end of my roadster. When I removed the rear end, I found the top leaf was cracked and missing about 50mm of one end. No problem, I'll get another from the leaf collection, or so I thought. Putting both side by side, the roadster leaf is longer than the others I have. They have all come from either tudors, tourers or utes, but no roadsters. I had a look at Marco's chart, but there is no reference to length of each leaf. Is there another chart with lengths listed, or is the top leaf for roadsters, listed as 7, the same length as other number 7's, but with the upper surface chamfered to fit inside the chassis?

I just refreshed my rear springs on a sport coupe and what I found was I was missing a few leaves/leafs? Depending on how many leaves/leafs your car is supposed to have you oh should be able to take even a Tudor leaf and make it work by measuring the length of your existing leaves and dividing the distance?? I wouldn’t think the thickness would make much difference on one leaf? I say this assuming you don’t have access to another set of springs to pull from. I rearched mine and added two leaves and it rides much better but they are also lubed up now. I used a piece of webbing strap (greased) from a ratchet strap to go between the top leaf and the cross member. It cushions that area some and I believe was advised to do in Les Andrews book although it says body welting (I think).

This is how much was missing from the top leaf of my roadster spring, with a standard length top leaf from an eight or ten leaf pack, and a replacement I scerfed the edges on a leaf from a set that matches the length of the original one.

I’d bet there will be no noticeable difference other than positive.
