I also work on cars, trucks ,motorcycles, ect. and found chinese parts to be a pain in the ass some work some don't. The term same but different comes up a lot with chinese shit and if you are willing to fabricate everything you use the china alternative may be your choice . There is a reason (original equipment manufacturer) OEM parts may cost a bit more they fit properly without all the modification , and usually last as a "good" repair should ! Professional people that use cheap chinese shit as cheap replacement should always wear there mask !
