Head unit install in a 98

I've got a new-to-me head unit on the way and I'd like to be ready to put it in. I've installed a dozen or so in various cars, but I've had instructions. Most of the write-ups on here deal with 2nd gen trucks. Anyone have any good instructions on a 1st gen, preferably an earlier 1st gen?

Doing some searching I found this writeup which isn't bad, but it doesn't get into details of putting in a headunit: http://www.customtacos.com/tech/index.php?article=77

I have a harness on the way, but do I need an install / trim kit? Does it use a DIN sleeve or bolt to the side against existing brackets? Just looking to have all my ducks in a row so the number of surprises are minimal on install day.

 

Bump. I finally got around to installing the headunit. It does not fit properly with the factory bracket. It does bolt up, but the placement of the screw holes is such that the headunit sits too high in the dash and thus is not able to open. I'm planning to tear it back apart today. Has anyone else had this issue? Do you need an aftermarket kit to install a headunit into a 98?

 

i would imagine you would need a dash kit i got to have on for my 03 ill post pics in a few days when i get home from afghanistan and ill do a write up on the first gen installs

 

I took the dash back off and adjusted the screws. The headunit now opens, but it's still a struggle to hit the button in the top left (Alpine 9887). I had to file down a couple nubs on the pocket so that the headunit could be angled down just a fraction of an inch. The fit is still substandard with a gap around the edges. The trim ring will not fit in this case as the gap is not quite that large. I'm curious to see how other aftermarket decks look.

 

i should be home in a few days and i will post my pictures of mine when im done, i am almost 100% sure you need a dash kit they are cheap as hell so go get one

 

Actually I went to Best Buy today to pick up a kit but they told me they don't even carry them. They just reuse the factory bracket and "make it fit." At least my labor is free! If I'd paid someone to do this, I'd be pretty peeved. I'm still considering ordering a "universal" Metra kit.

Hopefully the dash is the same in the 03 so the comparison is valid.
