finial cooling system fill 6.5 gl. Rear pads replaced, they were paper thin. Just a few miles from metal to metal. Left to do, bleed brakes including the abs module. Trans and diff service yet to be done.
Haven't tried, gonna have to give it ago and see.Does it do two wheel burn outs?
I had the rear view camera style in the 74 k5, works good for meI've actually never done a double din stereo my self. For that module, in them years I think it's just needed for OnStar. Not sure. I know in my 08 Denali have the dash went through the radio, and you HAVE to have a special module for that.
My 05 I just wired everything from scratch and I don't use OnStar so no advice there.
As for backup camera, I'd do one of the ones that is inside a rearview mirror. Looks like a normal mirror most of the time, and when it's in reverse half of it becomes a monitor. I personally haven't used one yet, so no idea if they're any good. But that's what I plan to put in my dually.
