Need a how to

[Ricoch3T]

Whats the best way to go about making some boxes to cover my 4 bar setup?
I've tried making something similar to what the ones look like that DSE has with the quadra link but they never turn out very well. Mine are longer obviously b/c I'm using a parallel setup.
I can make the boxes on my metal brake, which is the easy part. The part I can't seem to get is the front section with the curve in it. I've seen some people on here a while back that had some that looked pretty good but I can't seem to duplicate it and patch it back to the stock floor without it looking bad. I was going for the "factory" look when they are put back in.



Any ideas?
