I'm not sure Tim, but you really should own a 73 Buick Chassis manual. You can get them from a variety of sources. It should have been the first thing you bought after the car.
The 1973 manual is here if you're willing to page through the electronic version. Better to get a manual yourself as Larry already mentioned. http://boattail-riviera-by-buick.com/library/documents/1973 buick chassis sm/index.html Devon
I like the color diagrams that come laminated from Classic on Ebay. http://www.ebay.com/itm/1972-1973-7...07128996&pt=Motors_Manuals_Literature&vxp=mtr
How about this one? http://www.ebay.com/itm/Genuine-197...384?pt=LH_DefaultDomain_0&hash=item256f427198
Thanks again Larry. I couldn't find one nearly that cheap when I was looking. I hit the " buy it now".
Good Move. That is dirt cheap with free shipping. It doesn't get much better than that. Lots of great info in those Chassis manuals.
