Hey Phil,
If you have any issues let me know and I maybe can help you out. I have built 20-25 buggies and started when i was 12-13. My dad was the area VW guru and always had fast buggies that he built. I had a fiberglass body buggy and a rail both that I built when I was 13 or so. I think we used to have around 150 VW's all at one time in various pieces and stages. We used most of them for parts and pieces. My father owned a wrecker service and service station for 35 years and I bought all of his VW stuff before he sold out and I ended up having a couple more rail buggies and then sold everything I had to a neighbor for about double what I paid for it. Now I wish I had it all back because it would be worth a fortune. Oh well...can't keep everything! I am always willing to answer any questions that you may have, if I can.
Looks like a fun project too!
