Flint built
(Z84) Cheyenne equipment
?(686) Custom Trim Combination
(YG8) Special Promotional

Unfortunately the original rear bench seat was recovered and the front seats are long gone. Currently in primer. On the fence between going back to mostly original or custom.

Yes it is and nicely equipped. The Flint built examples don’t call out “Highlander Plaid” like the St Louis built examples. My guess would be orange plaid but the RPO is obscured. Is it possible the rear seat has an OE cover underneath?

Is there an example of a different color plaid than the original body color?

For this one it looks as if the third character from the trim RPO was a 6 as in 686 orange. It’s a good question, off hand I’m not recalling any orange K5s with gray, green, or blue plaid but they’re all blending together as time creeps by :)

Note the glue where the posi decal was located on the RH rear wheel tub. Also, spots on the floor pan where the rear bumper gravel guards and top to bedside brackets were painted.

Did that happen at the assembly plant or did someone just use the floor.

At the plant I believe (Flint). I've seen other examples but haven't bothered to post them. St Louis painted the top to bedside brackets white so there's some plant to plant variation.
