Thank you BEVIS KING&SUNDAYSHUNTER for your help on the centerbeams.
My car must be old as it has no Kadee pads. I'm going to have to do a lot of careful measuring to get this right.
These cars should have lower shelf couplers. For those in the more modern era where these are used,go to this link. https://www.dropbox.com/s/brli...%2011.27.03.jpg?dl=0 Wish I could get more info on these plus a release date as well as pricing.
Thanks again gentlemen.
