Do anyone have a part number or retailer that sells a drive shaft loop for the rear drive shaft of a K 5 blazer?

 

Nobody makes drive shaft loops for K5's.

Best bet is to find a local shop to fabricate one for you if you think you need it.

 

I had a forward U joint fail on a K 5 once when I was doing 60mph. I thought I ran over a roadside bomb. I almost shi+ my pants. I thought the drive shaft was coming through the floor-not fun. I would feel safer in my current truck if I knew the drive shaft was secured a little better. Thanks
