We stretched the seat cover bottom over the foam before we put it on the frame. You can get the cover over the foam if it's already on the seat frame, but it's not as easy. | 
Installing hog rings is pretty much as easy as using a staple gun once you get the hang of it. Just make certain the upholstery is pulled tight and even before securing it to the frame. | 
Don't forget to hog-ring the seat adjuster cable; otherwise, one side will slide and the other won't! |
By using the piping as a perimeter guide, you can pretty much ensure a nice, even fit like this. And if you get a little uneven, just remove the rings in the troubled area and adjust accordingly. | 
We redid the seat backing in the same fashion with equally pleasing results. Since the foam on the back portion of the seat was in good shape, I didn't have to order a replacement piece. | 
Can't say the seat looks any different than if I'd had it professionally upholstered (that is, of course, unless it was done all fancy-like). LMC's seat cover kit fits like a glove, and as this is being written it has held up to my daily abuse without incident. |

When ordering the front A-pillar trim, LMC doesn't have a part listing for pickups, but they do for Blazers/Jimmys (PN 38-2066/67), which fit just like the originals. | 
For the remainder of the interior paneling and trim pieces, I used the old components. Being dark red, since the new interior is black and gray, I had to dye the various items using the SEM products shown: Vinyl Prep, Landau Black Color Coat, and Satin Clear Color Coat (just in case the black was too shiny). |
