I can only comment on Goodmark. It is a great company to deal with. Service and availability is very good, as is quality. They are right on with there size. Perfect fit!!!
Careful with shipping. They showed up at my door with a $600.00 shipping bill. I had to refuse them and call the shipper. Finally worked aprice to $100.00 from Va. to Pa.
It is straight forward to hang them, but you may have use a 2x4 in places to tweek them into place, be careful where use push on as they are only sheet metal and can dent rather easily. As long as you push on a supported part of the door ie. where there is a seam or doubled metal, you will be fine.
As far as patch panels go, these pcs. require a great deal of fitting. Right now I am putting in floorboards,"A" and "B" post lower,kick panel, front body mount, rocker panel and lower rear 1/4 panel patches. All require a great deal of patience as mounting them reguires a great deal of time, but it is worth it in the end, or you can pay a body man a large sum of money!!
Goodmark is the only company that can make exact fit parts, they are an OER manufactor, licensed by GM, they are pricey but you get what you pay for. Only ship by truck as UPS will not cover any damage on over size packages.
Give me a shout if you need any further advice... J.
Careful with your latches, I have seen alot of doors dented on the inside top where guys have used their shoulder to force the door open, don't do it, it dents very easy, make sure they open and close easily, it will save you from getting pi$$ed off!!
