Well, so much for using my parts resources. I pulled the starter from the parts engine this afternoon but I found that housing was broken around one of the bolt holes. I figured that I would just chance the solenoid but found the starter currently on the 93 to have a crack in the housing. So... it was off to the parts store. Here are my findings for the different starters:
The starter on top is from the L27 and the one on the bottom is off of the L67. Other than color, they look the same to me. I couldn't find any part numbers on either so I can't tell if they are replacements or OEM equip.
Here'* the L27 on the top and the reman Delco unit on the bottom. As described above, there is a noticable size difference. The reman unit reminds me of a large caliber canon shell. It'* pretty cool looking. The reman starter was $172 plus tax.
