After letting the glue tack up, Mario started at the tunnel and then worked outward to lay the carpet for the final time (notice the weights are being used by moving them to the immediate area Mario is working on). | 
With the front completed, Mario then worked on the rear half of the cab. | 
To fit the carpet around the Compushift computer used to control the Big 10's Gearstar 4L60E, Mario trimmed the QuietRide kit to allow the wiring to sit flush. |
Then a horizontal slit (not vertical!) was used to fit the carpet around the Compushift computer (the same would be done to fit an amplifier, etc.). | 
With the initial test fitting accomplished, the next step was to coat both sides with glue. Then Mario was ready lay the rear of the carpet for the last time. | 
A single-edge razor was used to trim the carpeting away for the bolt-holes. |
Notice how vertical slits were cut into the edges of the carpeting to make them pliable enough to tuck in. This is step is critical to producing professional results. | 
These weights were a handy tool as well. | 
The seat adjusting control cable (wire) on the Big 10's seat was hanging freely and presented a possible future problem. Mario attached it to the seat springs with a couple of hog rings. |
From start to finish it took Mario about two hours to install the TrimParts molded carpeting kit--double that time for a greenhorn. | 
The finishing touch was a pair of matching TrimParts floor mats. |  |
