Ok I'm thinking bout changing the Diff ratio in my EL Wagon, she has a 323 "Standard" I bought a EL XR6 sedan as a donner car ( I'm putting the XR front on my wagon etc.) it has a 345 LSD, would the internals of that fit into my wagon?? And besides the RPM change what benefit would I get by changing the ratio??

the internals should/will fit and as too what benefits ..... betterer take off!. fitted a 3.45 to the old 'yella peril' and it made a noticable improvement to it. won't be that much of a rpm change.

Thanks for that, even though I fitting a series 2 AU 4ltr in her with cam & chip in the ECU ( mainly for towing) the way she is now it gets up and go's uinreal and like you say will have better "Take Off" plus I think having a 345.1 would be a lot better for towing a caravan.

putting the 3.45 in yello peril has me wanting to put one in the EB wagooon
