can you get blueprints of a 1975 4905 bus ???

[Lonnie time to go]

Just wondering if this is available anywhere.
Hopefully in full detail so you can clearly see what every part does on a bus.

The short answer:  No. 

GMC has never released that type of information, and probably never will.

Heck, the Corvair restoration folk have been trying to get copies of the Fischer Body assembly manuals for years, to no avail.

The closest thing to what you want is the parts book, which is a must anyway, along with the shop maintenance manual.

Doug (tekebird) Wotrig might still have some copies, otherwise you can get CD versions from www.coachinfo.com.

BTW, what's the VIN on your new toy?  P8M4905A - XXXX

FWIW & HTH. . .

Coachinfo.com has some original copies of the GM Parts Book for that S/N that includes drawings of the parts and their assembly. They also have a CD which includes that manual as well as the Maintenance Manual and Operator Manual.
