Are there any baseplates smaller than 8x12? I really need one that is 6x16 but don't want to use an unofficial part.
No, I don't think there is.
The only one I can find is an extremly uniqe 6x6 baseplate
in this set
off topic Michael, but do you have an email? THere's no way to contact you on this board to tell you I have all of those computer images scanned in.
Which images? I am not a parts author BTW.
