Thanks for the pictures and help everyone. Except for a few bits and pieces still to be fitted, my HL Tiger is now up and running. I'm only having a problem with the gun elevation not working. This is due to not understanding where the second red wire from the elevation motor goes. I'm not bothered at the moment, as The top will have to come off again as soon as the Clark electronics are available in about April.
Everything else works just fine, and with the metal suspension arms/wheels/tracks, she is running better than before. As soon as I get the chance to fit all the remaining externals, I'll post a few pictures.
Once again, thanks very much for the advice.
