The smaller shifter (I used a '68 Mustang) will fit on the smaller tunnel and look right at home there, without the hump. Bob is right, the hump would have to be modified, and it probably wouldn't look right. If you have the smaller shifter, go with it on the floor, and save a buck or two.
The answer is ??? It had thin head bolts in each corner. The plate was about 1" wider/longer than the shifter bezel. The shifter was broken so I let it stay.
that fat front bumper looks mint except for the missing bumperette piece. Too bad no one wants those...
