If you don't have Solidworks I'm sure if you give Jason an email he'll export it to a file that your software can support.
There's more to suspension design than making it "fit" the Haynes chassis. My dealings with the Haynes's supension shows that as the car rolls it goes into positive camber, not ideal.
Spend a bit of time to get it right, you'll be far more satisfied with the results.
