how to install the flex plate and torque converter
as far as converter bolts...there are two different thread sizes...5/16 for stock style converters...and 7/16 for aftermarket/performance style converters....
if you are using the stock flexplate...should be 5/16 thread size...9/16 wrench size...the converter bolts have a narrow head as not to hit the back of the engine...
the crank to flexplate bolts are all the same 7/16 thread with 3/4 wrench size....
use a thread sealant on all those bolts...
