I was in the same dilemma as you a while ago.
I'd recommend the TC skid first though.
I looked all around and finally had to decide between rusty's and skid row's. There was a dollar difference, but if you check around you can get both cheaper.
I went with skid row's because it looked beefier, and it also provided a hole to drain fluids.
I was not disappointed when I recieved my new plate. The welds were flawless, and the plate bolted right up.
As for the gas tank skid, check every boneyard you can, you won't be disappointed.
I found one for 5.00 (I already had one, but wanted to play...see my prior post about modifying gt skids.)
Go to the U-Pulls, cause the others just overcharge.
HTH,
John
