no, 1967 was the first year of the coronet R/T.

none as the SE package wasn't offered on the R/T model coronet.

go to manheimgold and figure out the price.

On some pre 60s cars it is located under the vehicle below the driver's position floor. There is normally a panel you remove to access the master cylinder. The brake pedal lever connects to the master cylinder so just see where the brake lever is connected and see where the lever goes. Follow that and you will find the master cylinder.

about $3,300.

Better position is to be on the floor wells (where you place your mats)

then on the bottom seat (one side at the time) push down and back at the same time,then pull it foward, there is one clip on each side, I recomend to do one side then the other,

remember to to push down and back to disengage the clip,

one you remove the bottom seat you will see the back of thr seat where it hooks, good luck! ones you know how the clips get together is very easy but it may look a little frustrating the first time so be patient,although cursing always helps.

If your talking a coronet R/T they are pretty rare today, even an automatic of 68 or 69 is rare.

It is 4.5".

look on drivers side to the left of the steering wheel up under the dash, if not there open glove box and look to your left.

depending on the rear gear ratio usually around 18 to 20 MPG.

I don't believe it had a fuse panel, but you may find some inline fuses.
