Universal joint

Just start calling parts houses, driveline shops etc. in your area until you find one that carries the Combination U-joint 7260 to 7290 style--- Spicer 5-527X, Meritor CP527X, Precision 347, CR UJ347, TRW 20226, Napa NUJ240-0369, Neapco 2-0527
I try to only use Spicer as my experience has proven that they hold up better. Your experience may vary.....
