replacing exhaust manifold

[rddaves54]

I found a set of exhaust manifolds on eBay. They say the quality is good and will be as good as others offered. I was wondering what to look for in buying exhaust manifolds and if anyone has bought from AM-AutoParts before or bought their exhaust manifolds.

The ones I took off today are pretty well shot.

Here is what the add said.

I have bought re-popped exhaust manifiolds on E-bay and had no problems with them.

One thing you need to know is there are a few different styles. Some are straight down dump and some are angled back. The stock 2wd trucks had them angled back & 4wd had them straight down. I've also seen something mentioned about a bracket that needs to be ground off on replacement units.
Hope this helps.
