Does anyone know the size and length of the low pressure return line on my 88 K5 Blazer ? I'm looking to get a braided replacement line, not too sure who manufactures this type of line, but I also want to replace the steering box bolts with a Grade 8 set. Mine keep coming loose. I already welded in the frame support kit that is sold by LCM and it works pretty nice. But I need to know this details first. Thank you !
