shopping for chassis
Be careful there is some real junk out there forsale.I spent a year and a half looking at numerious cars and ended up buying a moly rolling chassis from a well known reputable builder.I like you did not need a double framerail moly car because Idon't intend to go that fast right now because of the exspence.However you never know what the future is going to bring and its going to be nice knowing I can throw anything at it and the car will be able to handle it.The car is so square its incredible,the welds look like rolls of new dimes.
Now to get back to you, make sure the car you are looking at is on a level surface.Take a tape measure with you and measure the chassis from front to back and side to side.Pay close attention to shock adjustments there should not be a great difference in them.Also 4 link adjustment should not have a great difference from one side to the other.Don't forget no powder coat.I seen one car that had the welds bondoed.Being confident in your car is worth its weight in gold.
