Uncle Chuck –
The block is not 3″. The threads on the u bolts are completely ruined on the ends. Not one bolt will thread on. The length is too long. I had to buy a 30 dollar die to fix the threads, after cutting off the worst portion. Cheap, Chinese, low quality, crud. Don’t waste your time or money!
