rear brakes for Walter

[rcarlisle]

I would like to pick up my brake shoes tomorrow and have them Saturday morning to start my brake job.   My question is how to be sure which size without having to remove the wheel.   According to the chart in brakes section, http://www.garysgaragemahal.com/brakes1.html, I should have 11".  Is that correct?  

81 F150, 302.  2wd.   Ford 9", unless there is another axle that looks like a Ford 9".   Definitely not a Dana or anything like that.  

Can one of you wizards confirm that?

Thanks

Yes, the catalog says that all F150's take 11 x 2 1/4" shoes.
