This looks like an incredible deal for someone looking to build a vintage Trekker:

The toppers never last, you will for sure need to buy a new one from Slacker, mine has deteiriated so bad, you never get all the cracks fixed. They used some pretty low grade materials to build these back in the day. I have done so much work to the rear tub of mine im hoping its going to good, but my topper was so bad it was beyond repair. And so far every trekker I have seen has the same cracks and splits in the same places.
