Need some A-100 straight axle advise for a 66-valiant???

I want to turn my 66-valiant into a straight axle gasser street/strip car.. I have a complete A-100 straight axle.. I looked through a bunch of the past posts and couldn't find any straight axle 66 valiants (this is a huge web-site to seach through)... I can do all the work myself, I just need a little guideance and advise (so I don't get killed)... If anyone has any pics that would be awesome... I haven't drug out the tape measure yet, but the axle looks a little wide for the 66.. Any advise would be greatly appreciated... Here's what I'm starting with...
