Yes, the nine inch will fit in a 289. The vent must be move from the top to the back to prevent interference with the upper sheet metal on the rear tower. I always set them up with a vent bung on both top and back and just plug the one you don't use. As for install it is a direct bolt in no cutting or welding, if the frame is to original specs. You are correct on gear changes drop the drive and half shafts, pull four bolt on the houseing and drop it out. Then it is just like changing a nine inch third member and reinstall the housing. If If I remeber correctly we were doing it in under an hour. Also if I am not mistaken to change gear in a salisbury, if you went above or below 4.11 you had to change the carrier also $$$$. As for George he is a great guy and one I have known for years. I don't want to get in a bidding war but I have parts for about 20 of these rearends and I only have two Cobras so I will make sure I am competive on any apples to apples set up for these parts. The price I quoted was for a complete housing, Third member (NEW PARTS) your choice of ratio w/locker, stub axles, bearing/seals, and hub yokes. If this becomes an option which people are interested in we can also go back into production on these with no problems.

I will post a photo in the mourning as well as e-mail them to all those who sent PM.

Thanks for all the interest everyone,

Mike
