Thanks for posting that photo Mike, that will help those needing a alternative to the methods already being used for the sump mod.
With this mod you show, will a RB20/Z31 pan just sit right down on that block with out any mods, or are the usual mods still needed to the rim of the pan, to bulge it out around the added pick up mounting flange?
Please explain the baffling mods needed, if any, to the pan also, if you can...
Thanks again and nice job on the fabrication.
