Try putting a WTB advertisement in the classifieds section of the forum. Drew or someone might have have one and see your ad there.
Some info in case you didn't already know:
The part number of the 1993 TCU is either 31036-64U20 or 61036-64U75.
The TCU you want comes from a car made from 07/92 to 02/93.
Copied from another post....
"The TCU you want is from a 1993 model year with part number 31036-64U20 or 64U75. Later 94-96 TCUs will work too, but the transmission in those cars are geared differently than the one in the 90-93. For best results having the matching ECU is a good plan... you tend to get better redline shifts..."
"The difference between the 64U20 and 64U75 is the U75 was a counter-measure TCU that was installed to reduce torque converter shock in vehicles built before 2/1993 (VINS ending in 250083 or before). The TSB is ITB94-023.
The countermeasure part numbers for 1991 and 1992 models (2nd gear start) ended in 64U70 replacing 64U11 and 64U12 factory TCUs. Apparently this wasn't an issue on the 1990 transmissions."

Where are you located? If you're lucky enough to be in one of the cities with a www.pullapart.com or similar style yard with a '93 in stock, that's your cheapest option...
