I have a BJ40 with a 3B Engine, and i'm modifying it with Discbrakes allround, power steering, 35inch tires and Coil Springs. because of the coil springs, the BJ is much taller than it was and the u-joint of the front prop. shaft on the T-case side is almost on it's limit. what is the solution?? a double cardan? or grinding the u-joint in order to get a little more angle? if the best way is the double cardan where can i get one or which toyota use a double cardan that fits the BJ40?? Any opinions on Simex Extreme Trekker tires??
