Here is a reprint of the Ford directions for doing a rumble conversion. It is from a 1968 issue of the Model A News (issue #6 I believe).
I have edited it and removed some pictures and maybe some text. I wanted to slip this into my web page on rumble seat info, but I have some formatting issues to figure out. It looks like you could really use this info right at this minute.
Reprinted from Ford Dealer and Service Field Magazine with comments by Ed Francis
all the parts usually necessary to install the rumble seat, including back cushion, seat cushion, rubber floor mat,
coated cardboard or fibre sides, step and bracket for rear, step to go on fender, offset hinges, metal floor plate, screws,
bolts, etc. In 1929 the Company pro*duced 99,754 of these kits, in 1930 there were 125,126
produced and in 1931 there were 35,064 standard
kits and 775
deluxe kits. (How would you like to find a few of
these?)
[FONT="]DOING THE JOB[/FONT]
A good preliminary to installing a rum*ble seat in the Model "A" Ford is to study these instructions. Some points may not be quite clear. So the second essential is to study the "parts" which are to be used in making the installation. While the third step is to study the car itself, and the con*struction of the rear deck. Also, if you wish, to mark with a piece of chalk, the screws and parts which will have to be removed.
We suggest that the two steps be in*stalled BEFORE the job is started, so that there will be less chance of damage to fenders and body lacquer.
The lower step is bolted to a forged steel bracket. This steel bracket is at*tached, at its front end, to the rear of the two horizontal bolts which hold the fen*der brace to the chassis frame. The other
bolt, which goes through this bracket, is a vertical bolt through the corner of the rear cross member of the body.
The other, and upper step, is fastened at the top of the right hand fender.
The usual assortment of mechanics tools will be sufficient for all the work — with the exception of fitting the door latch or lock.
The lower edge of the floor pan as*sembly is distinguished by the "drain holes" (at the bottom of the four rein*forcing ribs).
Notice that the horizontal slot, in the front edge of the lid through which the latch projects, is "off-center" with rela*tion to the round hole for the handle of the door lock.
1. Open rear deck door, and remove by taking out hinge screw A-20910 at each upper corner. Remove hinges from upper corner of deck opening.

3. Remove rear floor pan assembly, taking out six screws A-20552, six nuts A-21661, and six lock washers A-22150 in front end. Remove support for pan at rear edge by taking off six screws A-20210 and six lock washers A-22088. Remove bolt A-21144 from tire carrier bracket support, nut A-21795, pin A-23531.

Use bolt A-21136, nut A-21795, pin A-23531, through floor pan into tire carrier sup*port.
8. Install wood slats — deck card*board retainer lower, A-52662 in Coupe, and A-41662 in Roadster (using one screw A-20224, one nut A-21572, and lock washer A-22088 through center hole in rear deck pillar. Use same screw and nut in the hole provided in front deck pillar. To fasten the front end of the slat in the standard Coupe, remove the seat back and loosen the side trim panel, and bolt slats to trim rail, using bolt A-20263, nut 21572, lock washer 22088.
9. Secure deck door body hinge A-52530 right hand, and A-52531 left hand in Coupe, A-41543 right hand, A-41544 left hand in Roadster, to rear deck pillar using two screws A-20709, two nuts A-21702, two lock washers A-22217 in each hinge.

Forward hole in step bracket engages rear fender iron bolt on inside of sill and rear end is bolted to sill at hole in corner plate at end of sill. Use plain washer A-22219 at this place on account of the large hole in sill corner. Assemble the step A-41563 to bracket, using washer A-22217, nut A-21707.
The question may arise, "Why doesn't the Ford Motor Company exchange rear deck lids, thus making it unnecessary to change the hole in the lid?"
Among the reasons why it is not usu*ally practical to make this exchange are: 1. In case the car has been in use for some time, the lid removed may have its finish more or less damaged by careless use. 2. As you know, pyroxylin lacquer dries almost instantly, in the brief time it takes the lacquer to travel 20 inches from the gun. Being so volatile, it is nat*urally hard to keep at exactly the same shade and, as a result, deck lids painted a few months later, may not be of exactly the same shade as the bodies. Even when all cars were black, some blacks were inevitably blacker than others. And with colors, these slight variations are far more noticeable. 3. Then too, there would be the expense of handling these bulky lids without damage.
Near the forward edge of the seat bot*tom of the rumble seat cushion, will be found two projecting "hair pins" of heavy wire. These wire prongs are forced through holes in the sheet steel seat. Then the rear edge of the seat cushion is pushed down, thus snapping the seat cushion into place in such a manner that it is held very securely.
To remove the seat cushion. First lift upwards on the rear of the cushion, and then the front edge can be easily lifted off.
The seat back is held in position by two machine screws, passing through metal lugs attached to the lower edge of the seat back. With these two screws taken out, the removal of the seat back is easy.
Following is a list showing numbers and names of all the parts. These parts should be checked off, according to this list, before starting the job.
