Aftermarket parts that don't fit/work right...

[ItsRandy]

I am sure I'm not the only one this is happening to. Why do we put up with it? I'm not going to name names but here are a few things I purchased that there were problems with and the supplier treated me like I just don't know what I am doing:

Complete wiring harness - Not really complete
One piece window kit - Doesn't install/fit as advertised
Aluminium radiator with electric fans - After installation; "Those fans won't cut it with A/C"
Gauge package - Inaccurate temp reading; "You can't install the sending unit in the head", their instructions suggest installation in the head
Sheet metal - just like OEM...Not!
Stainless steel brake lines - "Bent like original equipment"...Not!
Assemblies come incomplete (i.e. no bolts, brackets etc.)

Sorry about the rant, I'm just tired of spending hard earned money and getting parts that have been misrepresented by the suppliers. What about you guys/girls, tell us about your experiences with parts you have purchased.
