I have not brought this brace of Carparts the reason because I need them but to test them. I had a front built of Wiechers and have just done the test, what to bring from Carparts :)
The processing is very miserable, because it looks very cheap and is very poorly finished. Sharp edges, stiff to screw and the assembly is also more like a well thing. On the left side it is too far inside and right eg to far out.
For your benefit, I need not say much ... when you're just screwed it up on the dome top and not really connected to the body, can one also do not expect much. When they did not have installed.
I can only advise against this is to block.
Right after that I again installed by Wiechers and was in the end purpose amazed what you but gets more for branded products that also keep the up to expectations!
