need help finding info on narrowing a diff.

hello all,
sure could use some help!!!.
i have a 75 chev.monza "race car" that i bought.
it has been backhalved and has a narrowed diff of some kind.
it all looks homemade, the guy said it worked well....but it looks suspect to me.
is there anywhere that i can find the proper techniques to narrow them yourself.
i would like to see of it is safe to continue using it.
looks like a std. chevy diff.
i am researching that now.
any help is appreciated.
dave

Here is a link to a webpage showing how to narrow a rear end housing.

http://www.moparts.com/Tech/Archive/race/16.html

here is a link to a crankshaft coalition wiki about straightening a rear end housing.
You may get some ideas about how to determine if your current rear axle housing is servicable.

Here is a pretty good rear end narrowing thread from the HAMB..
http://www.jalopyjournal.com/forum/s...d.php?t=166574

There are some right ways posted as well as wrong ways, the wrong ways are pointed out by the guys posting the right ways..

I do know where there is a very in-depth, step by step rear end narrowing article on the ford muscle forum, but you gotta spend 20.00 to join.

I spent the 20.00, that's where I found alot of the stuff I used when I designed my table and fixture that I wrote about in the wiki about straightening a rear end.

I would have linked to that, but no one wants to spend any money.

That HAMB thread is a pretty good one.

be warned about the HAMB..... there are many "4 - 6 - or more" lettered foul words used there.

they even seem to make up new cuss words at times. LOL
