67 Rear end 5 lug conversion problem

[HookEm67]

So I ordered a 5 lug disc brake conversion and 5 lug rear axle conversion kit from ECE. To my surprise I found out that my rear end has been replaced somewhere down the line as the 63-69 conversion axles I ordered were too short. ECE is awesome to work with as they will swap them out for the 70-72 axles as long as I ship the incorrect axles back. My question is should I send them back (shipping will be on my dime and run me about $70, each way I assume) or look for another rear end that will accept the 63-69 axles? Do I have any other options? I currently have a non posi with 3.08 gears that I would like to upgrade to a posi with 3.42-3.73 gear ratio.

The housing you already have will accept a posi carrier so just change it and the gears. Buying a used differential is buying a pig in a poke. You don't know what repairs it needs until it's in the truck. In the long run it will be cheaper to return the axles you bought to ECE, install the correct ones and upgrade gear ratios and a posi center when you are ready. Drive Train Specialists has all of the parts you would need to do that. Cost is about $600.00.

Thanks. That's what I figured and am planning to do. Just kicking myself for not measuring before I bought. That's what happens when you assume...

if you already have the later 70 1/2 and up axle housing, you're swap just became a whole lot easier since those 5 lugs axles are all over the junk yards! send back the axles get a refund and get a set locally for next to nothing. My 2c.
