I have had the tranny rebuilt.
I have replaced the gas tank.
I have replaced the seats. Not because they needed to be changed, but because I wanted bench seats.
I have also changed the leaf springs, shocks, door and bed.
I am in the process of upgrading my snowplow light.
I also own a GMC serri 1500K stepside, but I love my Comanche.
I'm also putting on two piece stainless tapered running boards and a cab spoiler.
It's a great truck. I wish they were still being made, as I would buy a new one.
This is a Very nice Truck to own.
