transmission experts step inside

To a short one like found on 700r4 and older 4L60e w/o the mounted safety neutral switch

is this something that's easy to get to by dropping the pan? I didn't know how involved this would be?
And anyone have any idea where I can get a short range select shaft online to make this swap?
Thanks in advance
I found this guy on ebay selling used ones...is this a good price?? or is there a source with a better price?
