Ya- you.

What did you remove?

removed? heater box, radio, antenna, carpet, large door mirrors for one car mirror, spare tire carrier and rear bumper for a plank of wood. It has manual steering and brakes. Still has the 15" steel wheels all the way around with dog dish hub caps.

Most recent picture from this winter... LOL
