Five yrs ago you could buy one in this condition for $125-$150. Not anymore!

Here's a very optimistic Seller...and, he LOWERED the price from $595!

Looks like the first set of gauges is in good shape...except for the burned up tach circuit wire on the back. I think $100 to $150 would be more realistic in this condition.

Yeah...I noticed that, also after looking closer at the pics. I've tried repairing broken circuits, but I was never satisfied with the results. Repro flex circuits run about $90.

It's actually one of the better ones I have seen for sale, other than the circuit. It looks alot cleaner than my spare. My spare has a burnt trace as well.

I agree, the prices have crept up over the past few years.

I get tired with everything being "RARE", Thank you Fleabay.

I see it's gone. Someone from here get it?

Any burnt tracer lines are an easy solder fix.

I would agree on rigid circuit boards.  But, these copper tracers on flex circuits are sandwiched between two layers of Kapton film and it can become a little more messy trying to reconnect or bridge damaged/missing sections of tracers with thin copper strips (I've even tried using some conductive adhesive copper tape that I used to sell to flex circuit manufacturers).   Maybe I wasn't doing something right...but, I just wasn't getting solid solder connections that I felt would be lasting and they looked like a hack job.

With these flexible circuit boards being reproduced at $80 to $100 it seems that would be a more logical to go that route than to repair one. To take it one step further, it would be wise to find the reason it burned up to begin with. My experience is that it usually is the tach filter is faulty or one of the IC chips on the tach circuit board went bad. The last one I had to trouble shoot ended up being the chip on the tach board. After replacing this chip I replaced the flexible circuit board on the back of the instrument cluster and it worked like a charm.

Regarding tach filters...I bought a used, but calibrated, Corvette tach for a conversion on a Monte/Chevelle tach cluster from John @ Redline Gauge & Clock Repair (TN) about a year and a half ago. I asked him at the time..."Is it always a good idea to use a tach filter. I've read posts where guys say their tachs work with or without one. Others say it will fry the tach board. His reply was..."tach filters were installed to fry tachometers-gm's way to make money in the shops-you don't need them". Hmmm......

I ran a tach in my 76 Laguna years ago without a filter. In about 6 months it fried the flexible circuit board on the back of the instrument cluster. My understanding of a tach filter is that it simply dampens erratic signals and filters out erroneous signals such as spark plug noise. So my experience tells me that they are there for a reason. Maybe Redline Gauge modifies these tachs so a filter is not needed. But for factory original stuff, I would feel better using a good filter.

I was about to cuss and start in ranting about gougers...until I saw the NOS and zero miles comment.
Still seems crazy high, but maybe worth that much now.

I hate it when people don't include photos. Not clear to me by his description if that first item for sale is for just a NOS tach...or, the entire gauge cluster. If it's just the tach, it's only the second one I've ever seen for sale. I bought the first one about 2 yrs ago from my buddy who has the stock of NOS wheel openings. If it's the entire cluster, I've never seen a NOS one.

Seems a little out of line on pricing considering you can buy a 4-spd conversion kit from The Parts Place for $289.
