Factory ride height for a Scamp?

I'm getting new front end bushings (both uppers and lowers), strut rod bushings and a sway bar installed next week. It's got 318 torsion bars and XHD springs at the back with 235/60/14 tires. What is the factory ride height at the front for a 75 Scamp with a 318 and where is that measurment taken? The shop doing the work has a lot of experience working on older cars but I don't want to assume they know/have the specs for an A body when they do the alignment.
