"The guy who presently owns the car has purchased a lowering kit for the front and I'm not familiar with the kit. He made it sound like it would work,......... "

Cash, ask yourself...........
If it would do the job why didn't he install it before trying to sell it? This is like the guy who notes something wrong in his ad and then says "it's an easy fix". If it was so easy, why didn't he do it?

What you've described is a classic example of why swapping these later model chassis under much older cars, especially the "square" body kind, is not a good solution. Some very skilled people have pulled it off with a lot of modification, but most are done by limited skill dreamers who end up with a situation like you're looking at.

Don't fall victim to GFT!! That's Greater Fool Theory. The guy who built it was looking for one and found him. Now he's realized what he did to himself and is looking for that guy. Don't be that guy. Trying to figure out if a different clip, or a different lowering kit, or any other patch work change will work is only rationalizing a bad situation.

The only way this could make sense is if the body is really nice, it has a good title for a '34 Chev, and you only paid the value of the body. Otherwise it can't be cheap enough to be worth the trouble, there's too many other better choices out there. Even experienced people almost always underestimate how much $, work, and time it takes to fix up a car. If you have only the limited experience that your questions imply there's no way you can imagine what would be needed to undo this mess.
