I had the same problem with Crower lifters. They told me they would work but they didn't. A lot of folks on the tech lines don't know what works in a Mopar.

The offset lifter is a bit of an issue. For non offset lifters I just use the AMC roller lifters from Comp. They are inexpensive and they work just fine for most applications.

If I needed offset lifters I'd probably see if Morel has anything that would work.
