Nothing is jumping out at you that needs to be changed between the two? If it looks like a longer pushrod will take care of it the MP # is P4510640. www.classicindustries.com has it along with a very interesting/comprehensive Mopar catalogue which they will send for free when you buy something and you can see what they have online. Not cheap $79.99. Probably www.summitracing.com has it also & a little cheaper but check the shipping/handling on both as they can get you there. If your handy with taps/dies I wouldn't be afraid to fab one up just use good material
