I recently bought a 91 k5 and it’s pretty cool the guy who owned it before me dumped some money in the engine and the suspension but it needs a little TLC on the inside so I’m tryin to find some cool gauges that aren’t going to break the bank is there a website or a company that caters to k5 owners

Are you looking for stock or aftermarket?

My blazer is a 90 not a 91 and I’ve found a few places that sell guages but they are all around a thousand bucks and that seems like a lot but I’ve never shopped for guages before so I may be wrong and a grand is normal
 
Yep, pretty normal for aftermarket gauges. Keep in mind the popular thing to replace stock gauges before all these full replacements came out was to adapt autometer individual gauges into the stock locations.

If you were to price out the individual units even from summit you’d have well over a grand in gauges alone. You’d still have to cobble it all together. Some guys made it look great some missed the mark.

Put into perspective a grand for a complete set that fits and provides way more adjustment than stock or aftermarket individual gauges is actually not a bad price.

Keep this in mind too, electric speedo stock squarebody clusters have jumped in price due to guys swapping in late model drivetrain that don’t have any provisions for a cable speedo. Even the 2wd guys want them if they want to retain a 100% factory cluster with the modern drivetrain. I’ve seen them going for $500 and up. Again it puts into perspective the price on the aftermarket units aren’t outrageous.

My ‘91 came with the electric speedo cluster and with a couple of changes to the drac module I was able to calibrate the speedo for 35” tires and 4.10 gearing. It’s dead nuts accurate to GPS when I check it too.

What the LS swap crowd forgets is the stock cluster can still monitor oil pressure and coolant temp. They think it can’t and they end up buying aftermarket complete units. The thing is the stock cluster can do it. It did with my LS swap and when I swapped out the LS for an 8.1. I ran a second coolant temp sender for the cluster and one for the pcm. Oil pressure was easy just using the stock sender in the block. The 5.3 posed a little challenge as the stock small block sender is SAE pipe thread and the LS is a smaller metric size. I gambled and had a buddy turn down the stock ‘91 sender on a lathe, thread it with the correct metric die and it screwed into the head like factory. The 8.1 has the same size sae hole as a small block so I went back to the oem sender unmodified.

I’m just pointing that out to show one can use a stock cluster if they want/need to. If you want a new cluster with all the new tech and features that’s cool too. Just expect to spend some coin on them.

Thank you
 
Just FYI, the 90-91 clusters are now worth a small fortune due to the LS swaps.

How much of a fortune? I have 2 1991 and a 1990. Just pulled out the 1990 cluster and went to Dakota Digital. I plan on keeping the cluster as a spare for the 1991's. I figured they would be hard to get in the future being a 2 year special.
 
I see them on eBay consistently for $200+. No idea if they sell, but they pop up in that price range so frequently, I figure they must.
 
Oh they are selling for a lot more, I have seen some sold for $500 or more
That’s where you be seen some go for. Though 99% I’ve seen for sale don’t include the drac module or associated wire harness. I’ve pulled three drac modules and harnesses from trucks at the u-pull-n-pay that the cluster was already gone from. One of them was just yesterday.

I’m not sure how the ls swap crowd is using the cluster without the drac module. The drac is taking the raw pulse per mile signal and adjusting the value to account for the tire size and final drive ratio. Just running the raw value from the vss will not give a reading anywhere close to accurate on the speedometer. They might be feeding an adjusted value from the pcm but I’ve never looked that far since mine already had it.

But as was the case yesterday they had already yanked the cluster before I got to the truck. They clipped the harness for the cluster connector but sure enough looking through the empty radio hole in the dash I could see the upper edge of the drac. Pulled it out by had as it only has a big spring clip holding it in and spent 5 minutes removing the harness for the drac from the main IP harness.

Stupid easy to remove.

Astros used the same drac. Probably hard to find nowadays too, but they were far more common than the '90-91 R/V ones.

Pretty sure the LS PCM can output all the VSS needed to run everything, no DRAC needed. Simple, but I'm not swapping to LS to get rid of the DRAC lol.

I ran the drac with the 5.3 and still with the 8.1.
