Tony is right. From the appearance of the chassis and it's fabrication, the original fabricator did not have a firm grasp of space frame design geometry or construction. There is no indication what type of tubing was used for the chassis but I would bet dollars to donuts it was not 4130 or 4340. It is a virtual certainty it was mild steel tube. There are already chassis tubes that have experienced either some type of impact that bent them or the original fabricator did not use a chassis jig and something as simple as a measuring tape.
This car for all the reasons Mr. Mustang (Bill) has already mentioned, plus it's suspect and questionable chassis design not to mention the highly suspect fabrication lineage is not just a good thing to pass on it is a potentially dangerous vehicle to put on the road.
There is a difference between appropriately encouraging someone who is engaged in a tough but worthy project and blowing smoke up someone's arse about a mechanical aberration that minimally for safety considerations likely should not be driven.
The main chassis tubes on this frame do not look parallel up front under the engine. Is that because of an accident that would not allow the chassis to be properly repaired or was the tubing layed out that carelessly during fabrication? This is a stand back don't touch it car that may well experience a mechanical chassis failure at some time in the future — probably sooner rather than later.
While there are no close up views of the welds on the chassis tubing, if they are like the
oil pan, the car is an even more unattractive and very likely a dangerous choice.
The OP should have done his research before purchasing .
