David from www.Lextreme.com (http://lextreme.com) recommended and showed how to replace the starter bolts on the starter in order to ease the changing process. In the event of replacing a starter the factory long bolts must be removed from the rear of the engine. This means that you have to contend with the firewall as well as EGR pipe. In my case I will have an adapter plate (or ring) pressed up between the transmission and the engine. This will protrude out around the seam of the joining components so backing out the starter bolts would require removal of the transmission. Instead I just used Mr. Lextreme's trick and bought $5.01 U.S. worth of hardware to make life much easier.

The factory starter bolt is on the left and the new style is on the right.

Here is the list of hardware the I bought: 2 - G8 (grade eight) bolts, 10mm thread and 50mm total length
2 - G8 10mm nuts
2 - 10mm split ring (locking) black washers
4 - regular black washers
The thread length of the bolts can't be any longer than 46mm or else they will protrude past the machined edge of the engines mating surface (that comes in contact with the bellhousing). A total length of 50mm was just fine. The starter is also threaded so I just simply screwed the new bolt in (nice and tight) from the front and then placed the starter in position. Then the nuts simply secure it from the other side nice and easy. Now if I ever have to swap in a new one (lifetime warranty on the Carquest starter =] then I just need to remove the manifolds and back out the bolts from the front OR remove the nuts from the rear. How cool is that? Not very but it looks neat. Have fun.

The finished product from both sides
