I've working on fitting the 28in tall tires into the car.
They are just too big. I'm going to try some 26" tall tires instead.
They are a little thinner too, and should just fit better all around.
However, it still looks like the stock leaf springs are just not going to work,
and I'm going to need to put in a 4-link suspension and rip out just about all the metalwork in the rear of the car.
I suppose the good news is it will remove more weight, but this is going to take even longer than I hoped.
