[TR] Transverse Leaf Spring Orientation?

[Bud R]

A little more info.  This is a transverse leaf spring for a MK IV Spitfire and uses four studs to bolt to the differential not six studs like earlier cars.

Found another manual that says the spring clips are marked “Front” but of course my spring clips don’t have any markings. The spring has been de-arched for camber and the spring clips were welded back together not bolted back together. 

The manual also says the main spring leaf should have a ground edge and that should be mounted towards the back of the car but again my main spring leaf looks the same on both edges with no obvious ground edge. Strike two. Maybe on a race car with a de-arched spring it’s not important.

I didn’t pay any attention when I took it out since I didn’t know that was important to know and odds are it might not have been put in right by the previous owner anyhow. I don’t see any way of knowing what the front of the spring is since it’s not marked on the spring and there’s no obvious way of knowing what the front is. There is no difference in curve or bolt holes or anything I can see to figure this out.

I don’t want to get to the point of putting the vertical links, shocks, etc. back on only to find out it does matter for fitting everything back together.
