    I tried searching but I couldn't really find an answer. I am trying to install an ultramount on a '98 Tahoe 2dr 1500. The directions make it look like you are drilling out existing holes in the frame to mount the brackets but when I put the brackets up to the frame no holes match up. Is this right or are my brackets off?

    I just tried to refit. The three holes the in the frame the bumper mounts to do not line up with the three holes on the mounting bracket. Does that sound like my brackets are messed up?

    a lot. There is no way to get a bolt through to re-attach the bumper. They off at least 1".

    You did take the tow hooks off and the frame isnt bent, correct.

    No lead and i had some installs with that mount years ago where it required drilling or reaming out the holes on the truck to get things to line up. Wasnt fun, its not a straight shot because of the body mount.

    Part# 67865 I already listed it. Don't you reem out the mount and not the frame? I took the mount back and got a new one, haven't tried it yet. The installer at the palce I got it said Chevy 1500's were the worst and nothing ever lines up?????

    Reamed out the frame, usually the holes on the truck were higher than the mount holes and you want to be able to keep the mount up tight to the bottom of the frame.

    And yeah, the 1500's usually didnt line up.

    As for NO Lead not being able to read, hes having a hard time thinking lately since hes down to 9 7/8's fingers.

    If you ream out the frame won't that mess up how the bumper goes back on if I ever take off the plow? Won't the bolts on the bottom hold the mount up good enough?

    Got it on finally! Went OK except driver side nut plate had holes tapped at crazy angles and the holes on the plate on the bottom plate were too close together. What a POS!!!!

    Now I am on the wiring and just noticed I have no daytime running light harness adapter, even though I specifically requested one. Is this necessary or can I wire it up without it?

    You can make your own drl harness using a couple of spade terminals, some wire and inline fuse.
