Mike,
Very cool. How did you get the motor?????
I have an 84 GN with 87 drivetrain that has been "modified" somewhat.
Good luck on the 81 Sport Coupe. They have to be scarce as hens teeth. Have you talked to Richard Clark? If anyone knows where one is, he will. Also, Mike McCoy might be a good source. He has been parting out GN/T's for 10 years or more. Watch Craigs List too. Could an 84 or 85 be converted to 81 specs?
