The Cressida pump is a cast Aluminium thing so the pickup isn't interchangable onto a GE or GTE pump body.
I did a custom pickup for a buddie's 7MGTE Crssida but didn't take any pic's and neither did he sorry. (I asked last night when I posted this)
The GTE pump has longer internal gears for more volume per Revolution to cover the Turbo and Squirters.
You could use the Cressida pump but might suffer really low idle pressures as a result.
