Andrew, First off let me say I'm a Crazy perfectionist. It took me 4 years of research and building to complete my Ala Kart. I even contacted the owner and Mr. Barris. There are many, many things that need to be modified, scratchbuilt or changed. But then again I'm crazy but I wanted It to be right. The kit has no air bag system,the tono cover is incomplete and mounts wrong, there is no brake detail at all. The engine oil filler stem is on the wrong side of the engine. Plus much more. Many items were scratchbuilt because they don't come in the kit. Yes It's a lot of hard work but for me it was well worth it because I just love this car and wanted to do it right. It rewarded me Best in Class at the GSL.
