Sorry for this dumb question but can I know the use of this and what happens if I don't replace mine and how I know if it's time to replace it
Thanks

Check engine light. I will probably only change the front two. This is harder than I thought due to rust.

Was only able to finish the stop and "latch", as well as mount it today. Had to work at getting the vehicles started. Neither my powerstroke nor the Tahoe would start. But my dinosaur 1964 Lincoln sa200 welder fires right up. Go figure...

So far so good
But I see you replaced the whole rear bumper why didn't you try to build it on top of it
Will it work ?

liberal usage of pb blaster and run the motor good to heat it up, they should come right out. That's how I've always done it.

Because who wants that ugly pos stock bumper? I sure don't. I'm confused as to why you ask if it'll work? I'm building it to work, why wouldn't it?

I'm sorry sorry for the misconfusion I meant will it work if you use the original bumper not the one you are building now

I don't know, I could probably manage, but then all the welding would screw up the chrome and I'd have to have it re chromed or it would look like shit.

Plasti dipped the plastic pieces behind the back windows looks a lot better and did some regular check ups on things and need to check on a bank 2 pre cat oxygen sensor code I just got.

don't know what a super chips tune is like but I know it was night and day when I had mine tuned !

Who tuned it?

Finished the fabrication today. Now all it needs is paint. It's gotta warm up a lot more before that happens. Lol.
