Best sources for rear end

Lets talk rear ends (punkins).
If I am looking for a different rear end ratio, what vehicles can I pull a punkin from and use in my bus? I have a 88 IH front engine long bus. The rear is currently 5.38 and I could use something a little better for the highway speed. Nothing exciting. What vehicles can I look at that might have what I need? How do I know if it will bolt in? Dump trucks, semis, what?

thanks

I see you've started a thread on this. I'm not sure if ours are compatible or not, but if they are and you manage to find a better one, I'd be interested in your 5.38

first you need to find out which axle you have in the rear, then you can search Ebay for the right differential for your rear end, they are not interchangeable between different series rear ends, also you can do a google search for your specific (for me spicer N190) differential as there are many truck salvage yards out there selling them

Yay!! Got my 4.10 differential today, now to get it and the MT643 installed. Then find someone to buy the perfectly good AT545 and 4.78 rear

How much for the rear end? I went to a junk yard today looking and couldn't find one.

That's funny. I was thinking the same thing.

Try this web site www.heavytruckparts.net or just google medium duty truck parts and salvage. Why would you want to change out the differential? My bus has 5.38 gears and with the Allison MD3060 it does 1800 rpm at 60 mph in 5th gear I would change the transmission first rather than the differential.

I have gone with a 4:10 for my bus also. I think Kubla is right. I already have a spicer 6+1 which is 1-1 on the top end, just like a MT643. With 11r22.5 tires I figure that will put it a good cruising speed of 68mph. The MD3060 is a nice trans, but I think it would be a very expensive swap into an older mech diesel. I keep hearing people talk about it, but I would like to see it done and how much $$ it cost to do it.
