need help/advice on gauges

My 1990 yj laredo has the gauge package in the little trim area above the radio, and gauges include ammeter, oil psi, fuel level, engine temp etc.

i had heard that jeep fuel gauges were notoriously inaccurate, and I bought a replacement autometer gauge to slip in. Got it late last week and found out that it will NOT just slip in to replace the original equipment gauge. I bought it from Quadratec, and they said it was a direct fit replacement. not the case.

it looks like all of the gauges are just part and parcel of this long printed circuit board. doesn't seem like any individual gauges can be removed and replaced.

other than getting a new circuit board, what are my realistic options?
i'd prefer not to have to buy a whole new set of gauges to replace all of them.

how i fixed all my guages
ok here is how i made all my gauges work like new. (temp.,gas,clock, oil pressure, volts)
remove the gauge cluster, then remove the lugs that hold each gauge from the back of the housing. i used a small rotary tool with a small wire wheel attached, i then carefully cleaned the two posts of each lug(you will see what i mean once you remove the lugs). also clean any copper surface that the lug comes in contact with, for good measure go ahead and remove the bulbs and wire wheel the contact areas on the circuit board too. i promise once you take the cluster out this will all make sense. while you are at it replace all the 194 bulbs too, add dielectric grease to all electrical connections and also make sure you clean any corrosion from the main harness and where it connects to the gauge cluster.
one final tip, when you remove the small nut that holds the lug on the back of the gauge you may need a small flat screwdriver to gently pry the lug loose
