Aftermarket or Original Tailgate???

[super72bb]

I am looking a buying a nice original tailgate for my 1972 SWB Fleetside. However, it looks like it is going to be quite expensive. I have no problem paying the money on original parts if the quality is that much better.

So my question is. Can anyone tell me about the aftermarket tailgates out there like from Goodmark. I was just interested to know... Is the guage of steel the same as original and is there any visable differences with the aftermarket gates from the original ones. I saw a NOS Chevrolet a while back and it looked very solid. I am hoping the aftermarket ones are as heavy.

Thanks any info would be great.
