I think the smith blueprints are more of a guide then any type of real plan. I also had a set and found you can not trust the diminsions on the plans, if you do you will end up redoing it.

Speedway Motors sells a book to put their prebent chassis together, dont know for sure if its like blueprints or just a manual for their chassis

Also, has anyone ever bought one of these kits and how well did it go together?

Port City Racing in Muskegon, Michigan has a chassis blueprint and step by step video. I don't recall the price but do yourself a favor and get plans AND video. It will give you all of the info you will need.

My 2001 car is a Speedway Kit car. I'd really never started totally from scatch before, so I had a few mis-cues. The biggest problem with the kit is nothing is labeled as to what it is. I took the obvious parts (the big ones) and put them on the car and when I got down to the bars that I couldn't readily identify, I just started mocking things up and looking at what worked in the places that I had yet to build. My biggest gripe about the chassis is head room. I put the main uprights for the cage on top of the Square/rectangle tubing where the book said to bore a hole and set the cage tube inside (don't worry, I addressed the shear strength issue by putting a slug into the square that reaches into the roll tube). I still had to make the so-called trap door in the interior decking on the passenger side to get the IMCA required 12" min. window opening. In order to get enough clearance for my bucket-head under the roof, I had to recline the seat a bit. You DirtWorks guys would have a cow. I used most of the Speedway design for the cage and front clip in my 2002 car that I have now, I just made it 4" taller. I sat in a Dirt Works the other night for the first time, and it still had more room overhead.
