No they don't pivot in the same way but the instant centre would work the same way ie: the front spring eye of the leaf would be the IC same as the front mount hole on the ladder bar. What you will probably have to do is experiment with the height that you mount the front spring eye to alter where your IC lies on a line in relation to the centre of gravity of your car. This is where my experience is lacking, I can't give you a start point.
You might consider new tyres as well
Ive tried to find the book that has been recommended but all i can find is a website to chris alstons chassis works but no book
May be worth an e mail. Also try a book on setting up doorslammers by Dave Morgan.
Vince give Andy Robinson a call, he will give u all the advice u need, he is a very approachable chap but dont call him b4 12 noon as he doesnt answer his fone, 01256 880589, but as far as i know the angle is 3 degree's
Rock n Roll's been going down hill ever since Buddy Holly died.....
mines 5degrees as thats what the back of the gearbox flange was after leveling the carb base on the inlet ......Guy
Vince I'm sure these days the information must be on the internet as well. Look for setting up/drag racing/instant centre. You can then draw yourself two rectangles, one with standard ride height and one moved up. See what it does to the lines through spring mounts. I bet you find you can work with stock mounts but have to play with the traction device to get things right.
The most adjustable race set up is a 4 link and on that the IC can change but leaf springs can be set up to plant tyres...just make sure they don't unplant them! Also be totally honest with yourself about the intended use of the car.
Andy Robinson? Don't forget what car he started with!
PS. Dont forget that setting up a car for racing involves the front suspension as well. For the road that has to be set up to work in different situations so your rear set up has to work in conjunction with a road front set up.

Vince, this is for a 4 link but it explains the relationships between instant centre/CofG/ neutral line.
