Hello, I am new to the boards and have a question. I just picked up my first 88 T4 and I am pretty pumped. I have been wanting a T4 for some time now. This is not my first Tecate as I own a 84 T3. I am looking for a service manual. I have searched the forums and see they are out there, but is there a different manual for the 87 and 88 or does one service manual cover both.
