...A spridget will not even fit on a modern alignment rack.
Correct...however...
I found, in my city, one of the old time alignment shops (yes, they also have the new machines) with the big bay with a front pit. On the pit is a permanent ramp with the swivel plate on one side and the one on the otherside moves on a track, so they can adjust it for the width of the vehicle. I gave him the track of the TR3 and he said 'no problem'...asked about the Midget and got the same reply.
Only car I've rebuilt the front suspension on, so far, and needed alignment was the TR3. I decided I'd use the 'string method' to get it close enough to drive over to this shop. My DIY string alignment worked so well I still haven't taken it in for the professional alignment. That was two years ago. I've put a number of miles on the car and the tires are wearing nicely. No shimmy or shake either...so I'm not going to let anyone mess with success.
