starter removal 77 300d

[kerry]

I've got my 77 300d on jackstands, ready to replace the starter with the heavy duty model. I've reread many of the posts about the starter but most of the directions seem to apply to the turbo engine. The exhaust runs above and behind the starter with the turbo, but on the non-turbo it runs directly under the starter, in the place where most people seem to describe how they got the starter out through the steering rod obstructions.

Can anyone tell me exactly how to drop the starter from below on the non-turbo engine? Just looking at it, it does not appear to me that there is enough room to snake it in and out? Anybody done it? Haynes is little help.
I'm pretty sure I can access the difficult bolts but I don't want to unbolt it without having some idea as to how to proceed from there.

Speak up quickly, I'd like to get it done before the Broncos start playing today!
