I have started doing a few minor chrome additions to my 2007 Dyna Super Glide Custom. My question is this. In many of the installation instruction sheets they recommend using a torque wrench. Right now I do not have a torque wrench, but I am not doing anything major. Mostly adding chrome to the foot pegs, lifter covers, etc... Do I really need a torque wrench or these type modifications? I'm not going to do any engine modifications that require major rebuilds, etc. Just a exterior piece of chrome here and there. What is your opinion??? Thanks!
