Front end alignment is important on these cars to keep rolling friction to a minimum. To get the toe set correctly, I use this method that I borrowed from my stock car days. I made this pair of alignment boards in just a few minutes to use here, but they can be used on any car.:rolleyes:
I began with some old shelving I scrounged from a renovation project here at school. This is 3/4" birch-faced plywood, but I could have used any flat material. I cut two rectangles the same size (11" x 24"). I screwed them together temporarily so I could cut them the same. I used a screw, string, and pencil to mark a half-circle on the top piece (Yes, I marked it twice. The first time wasn't big enough). After cutting the half-circle out on the band saw, I marked and bored two holes equal distance from the bottom corners. I used a 2" Forstner bit, but this could also be done with a hole saw. With all the cutting done, I removed the screws so I then had two identical pieces.;)
To set the toe, I put one of the boards against each front tire sidewall, secured with masking tape, and put a pair of identical tape measures through the holes. Now the toe could be set by comparing the readings on the tapes.:3dSMILE: I use 1/16" toe-in on this car.
These boards also work on full-size cars; I have used this method on my coupe and recently gave a set of these to a friend to use on his Model-A coupe, also.:D:D
