Wrenchbender,
That is what is confusing to me. I don't know if castings made in August of 1988 could have been used in 1990 or later transmissions.
I will have to go and check the rotation in 5th gear again.
Dave,
Thanks for all the info. I agree that I would like to use the same size tires all around. With my planned use of the rack & pinion steering, I will have less turns lock-to-lock and thus less leverage to turn the tires. I don't know if anyone elase here has had experience. Like I said I have had one person tell me that 215 would be the max width, but I would rather have a 225 or 235 width and don't know if that will necessitate power steering. I am using a 235 6-cylinder and not a small block so it might be complicated to add power steering.
