School me on Buicks.

What does the 40/60 and the 50/70 designations mean on these?

 

Those are the series, the smaller bodied cars that would share a shell with the Oldsmobile would be 40 or 60 series and the big cars like the Roadmaster which would share a shell with the Cadillac would be the 50 or 70 series. You'll see a lot of stuff referencing what series the Buick is for parts interchange, since parts from the small cars often do not interchange with stuff from the big cars.

 

Here is a good example, these are both 1948 Buicks. The full fade-away fenders give it away. One is a roadmaster and the other is the smaller version the special. They are sometimes referred to as baby buicks.

 

Thanks for clearing that up for me.

 

I tend to dig on the smaller series more. My 57 and my 38 are both smaller series. It can be a very important thing to know when searching parts. 50/70 stuff is a lot of times longer than 40/60 stuff and not interchangeable.

 

Through the mid 50s, the series were: 40-Special, 60-Century, 50-Super, 70-Roadmaster.

 

Wheres the best place to get floor pans for '55 40 series?

 

Also, through 1942 Series 80 = Limited, Series 90 = Limited

I purchased a set pf floor pans form some one in Mass about 10 year ago. I can't recall the name, but the pans were pretty basic. They fit ok, but didn't have any of the orginal beads. Just a few beads for strength. After that, I just started making my own out of sheet metal.
