Greetings,
I have one of the ME bridges. I did not measure the ties as you are asking as I will be able to shim the bridge shoes to make the rails match. The big difference on the ME ties is that they have the tie plate and spike heads molded in place. The Quick sticks do not have any tie plates or spikes.
In this post:
viewtopic.php?f=5&t=1077 it is shown that the P:87 plates can be added to the PC board ties. I have considered getting a set and trying to trim out the middle section and glue the spike head outter section of the plate to the wooden ties with a tiny drop of CA. Note, I have not done this yet so i have no clue if it would work.
