I got my case saver months ago went to install it and didn't inspect tr bolts both had thread burs on them (clumps of metal on the thread) completely ruined my case saver mounting holes. Now I have to drill out my case holes and tap them for larger bolts. Not really SBLT's fault just a note of caution to always inspect bolts before you just thread them in more my fault than anyone's.
first time i've heard of a problem with the mounting bolts. been getting these bolts from the same supplier for years. if the bolts don't thread in easy, theres a problem somewhere. either the bolts are messed up or the threads in the case were messed up or full of crap. the case bolts should have a tap run through them to clean out any junk before installation. if a bolt doesn't thread in, you don't force it in. i always test fit my parts before i send them out
I always test fit my parts before I send them out..... A good sign you are NOT buying crap!
