Proper Distributor for HEI Conversion

I received this new distributor from RockAuto yesterday and wanted the opinions of people who have done this conversion.I have a 1970 Fury with a 318 2bbl.The car is otherwise stock and has 74K on the clock.
It came with a sticker stating that the warrantee is void if removed! Don't like that at all.There is also a small amount of up and down play in the shaft, but this may be normal.I can return it if there is a better alternative.I am on a tight budget and already have all the HEI parts and a limiter plate to do this with. I think I will get a Pertronix Igniter III round coil unless someone has a better or cheaper alternative. Any and all advice is really appreciated guys!
