Will a 9" fit and work on my SXT 2WD Reg. Cab?

Why are there different sizes ie: 11" v 9"

Should I replace both if one looks needy?

just got my truck 500 miles ago.

My tranny fluid was checked, smells burnt, shop recommended leaving it in instead of doing a flush...flush may cause it to slip at this point since the fluid is in that state?

Any experience with that tranny would be helpful too.

You always do brakes in sets, so if you need drums you do both ends of the axle. Same with pads, rotors ect.

Your glove box has the answer bout your drum size. Its a sticker on the lid or the bottom of the glove box, cant remember which at the moment.

I would think a flush would be a good idea but I dont buy autos so I have little to no info on them.
