You're welcome----with the halftracks, you can run into an unforeseen problem with the tracks because of the requirement to add track blocks. I very nearly screwed mine up because I didn't account for the height disparity. This will affect the height at which you'll want to glue the suspension arms,. If you glue them without the pads, they will sit too low, and the front wheels will "float". MAKE SURE TO ADD THE "PADS" BEFORE YOU GLUE IN THE SUSPENSION ARMS!
Ignore the stupid Photobucket issue with the "bandwidth" problem here---check back after January 25th and you should be able to see the photos at some point. You might want to read the text about the tracks on this page in the halftrack tutorial.
