      Thanks for all the ideas. I looked at the write-up on the '60 conversion on Wilcap's site. Depending on the  cost of the tranny this might be the way to go. I really don't need a beefed up transmission. I noticed the was nothing on the driveshaft length so I'm wondering if it will need to be changed. Also don't know if the Pontiac yoke will fit the transmission. Does anyone know if the Eckler's shift indicator lens will fit the Pontiac bezel?

      The wilcap adapter set up would allow the later transmissions to be used but like my 55 with powersteering it looks like the 3 point engine mounting set up would have to be changed and with that big steering box I'm not sure it could be done.
      I'm running a 3:08 ratio behind my original Hydro and the largest tires I could squeeze under the rear fenders and it  averages 15-17 mpg out of the 389 on trips.
      An overdrive would be nice to slow the engine down even more than the 3:08's do.
      Has anyone done such a swap?

      Summit offers the adapter plates to put a 700R transmission behind a Pontiac engine.
      What they don't include is what flywheel and starter would you use on our early 287 -389 engines that had the hydraMatic.

      I've got to think this over. I know you told me the transmission was working when removed from the Safari but that was 20 years ago so I'm not sure what would have to be done to it to make it roadworthy. New seals, new gaskets? Also I'm not willing to drive to Missouri. Not being grouchy just not sure what to do. Would you ship?
      The mechanic who was working on the unit I have now said he was unable to get the parts he needed to fix it and recommended another shop but also recommended switching out to an R700 GM with overdrive. I like this idea but not sure what it would take to do this and eventually the cost.

      Anyway, I'm going to be gone for about three weeks and will think about what to do. Anyone out there who has any ideas-I'd be grateful. Thanks
