Plenty of internet info. 11" drum 1.75 shoes, all except police and station wagon.

According to this doc:

https://www.gmheritagecenter.com/docs/gm-heritage-...

The front shoes are 2" and the rear 1.75". It does not appear (as quickly I read it) that the 'model' makes any difference.

The wheel cylinder bore is different front from rear.

Please read it yourself to verify this data.
