Thanks!

The drive size of the
extension makes no difference as to mechanical advantage. It makes a difference to the resistance of the system to breaking. However, the 3/8" ratchet or breaker bar on the end of the extensions will be less than a foot long, typically 9" or 10". So you would have to use a cheater pipe to equal the MA of a 1/2" drive 24-inch breaker bar. If you do that, you can easily snap off one of those 3/8" squares trying to break loose one of those trans bolts. (The starter bolt is really a trans bolt.)
When I did my clutch, I used 1/2" drive wobble extensions from Harbor Freight , plus a few regular ones, adding up to four feet or so, until I was behind the TC and I could use a cheater on top of my 24" breaker bar for maybe 3 1/2 feet of total lever. Made it easy. The starter bolts are simple to reach that way--to get the top bolts I had to droop the trans a tad.
Highly recommend you desist on 3/8" drive for this job--you're just as likely to break the tool as the bolt getting free if it is stuck good.
