Looking for a computer

Well all I thought this may be the best place to ask. I need a computer for my 92 Gmc Jimmy 4.3 vin w CPI 4x4 Digital Dash p/w p/l air cruise tilt wheel. Anyone thinks they may have one please post the service numbers here (all of them please so i may be able to even match chip numbers) and let me know. Now I understand this may be easier for you all if i post my numbers but since I dont actually know you personally I hope you understand that I wont in case someone tries to send me a wrong part just to make a few $$$. So I apoligize in advance to those honest people out there.
Thanks
