1970 Duster Distributor

It's not touching so I'd run it. Love that distributor BTW.
my problem is that I need to raise engine 1/4" per TTI header instruction from the 5' to 5 1/4" from top of k-member to C/L on cranks shaft. I am not sure it will hit then either but I am pretty sure I will not be able to pull distributor out, with out great difficulty!
