I fixed one up a while ago.
I highly recommend the blue ramp and to change out the pop bumpers to yellow and add Metal-mods taxi stickers. Really improved the aesthetics. I had planned on doing a hardtop on it, but got a chance to trade it at a good price. Did the ramps from fantasy... they are really good, though there was a batch where the bracket was installed upside down. Check them before trying to re-install or you'll be delayed waiting for a replacement.
