you will need about 3 ft of 3/8in extension and i believe top bolt is 10mm allen so a socket with10mm allen, breaker bar and about 2 or 3 ft of pipe to slide over the breaker bar.make sure that you get the 10mm allen in securely before applying pressure.oh! it makes it a lot easier if car is on lift.

Thanks David everyone says allen but I'm looking at a 17 mm nut it goes threw the bellhousing & screws into the starter itself Scott

There seems to be some variations on the hardware used. Typically it is an allen cap screw, but sometimes a mechanic will decide to use a hex head, or even the factory had a few variations from year to year or model to model. Main point is to try to get under the car, preferably on a hoist so you can stand up, and use a really long extension, I always ended up needing a flexible U joint on the end of that also to get the angle just right. Best tip is to try to get a long 1/2" drive extension and zap it with an impact wrench to zip it out of there. It's tough.

I bought a nice socket from Snap-On to get the bolt out. It is a 17mm with a ball type flex joint built in (3/8 drive). Part number is IPFM17B.

Ha Rick with that ball socket from snap-on did u use it with a extension or could you get it from the top side Scott

You need to get at it from below with a long extension as stated in previous posts, but this tool handles the angle and tight clearances well. Go to the Snap-On website for a picture.
