How difficult is the set up part??? Can't seem to find a local shop interested in doing it... Am a pretty good wrench, but this is just one of those things I've never done and I'm a little nervous about screwing something up.
Never give up!

So they kept that one.... Anyway - I'm hearing that there's no way I can do 3.08's with this carrier - how do I get a higher rear end for highway cruising? Do a complete rear end swap??? If I have to keep the 3.73's this thing will be a major gas sucker and is running too high at highway speeds.... Options? Ideas? Thanks! | | |

If an auto you could use a 700 or 200 and if a standard you could use an old Borgwarner OD unit or a T-5. The first two would give you a 2.61 final and the T5 would give a 2.98 final. Just something to think about since it would keep the 3.73's for trailer pulling or heavy loads but give shallow gearing for highway cruising. This option is more pricey than a R&P swap, but a lot more versatile.

I've found a complete rear end from a '68 Suburban that is supposed to bolt right up to my rig in place of the stocker. Apparently, these are pretty hard to find. The trans swap idea is a good one, but with the 3 speed 350 in now, I can downshift if I hit bad hills. Not likely to do much towing. Again, I appreciate all the input and have learned a lot from this experience.... More to come with the swap, I'm sure, and will report my mileage changes. Thanks again! Doctor Dogg (donny) | | |
