I have a customer with a 70 164 who wants to install one of our aluminum flywheels and performance clutch setups. We have used essentially the same setup on all models from the 544, 140, 240, 740 etc., but not the 164, and I don't have a clutch and flywheel to measure.
Assuming the same 6 bolt crank pattern and same flywheel ring gear as other models, our normal AL flywheel will fit. The question is the throwout ( release ) bearing.
Our AL flywheel is not as thick as the stock b20 flywheel, so we use a longer throwout bearing to compensate. Not knowing how thick the combination of 164 flywheel and 164 pressure plate is compared to a 140 B20 combination, I don't know how long the throwout bearing will have to be to compensate for any differences.
The customer is going to be doing his own installation and does not have the car apart yet, so he can't provide the measurement.
Can anyone help in comparing the dimensions on the 140 B20 flywheel and clutch to the 164 B30 flywheel and clutch?
