Mk, Whre do you measure from for the ride height.
been told a few different places.

1) just before the rear wheels on the floor pan
2) Front just before the engine bay.

3) Just after rear wheels on the floor pan
4) front just under the centre of the wish bones

I would think Bottom of chassis (or Lower protrusion)
This only for clearance purposes.
Someone with more experience may chime in later and correct me.
I have my chassis on Wooden blocks @ what IŽll consider Ride Height.
4-1/2" at the front (Below the second bottom tube of the chassis.
and 5" At the last cockpit tube right befor the uprising tubes.
My suspensions elucubrations were performed considering this.
I am by no means an expert (or much less for that matter)
HTH

It will make little difference, I would think, this is probably why you have two answers. From what I recall bottom wishbone horizontal for an Mk == correct ride height, back end about 25mm higher than the front.
