She's one of my favorites.
The best view of Phyllis is in "Famous T & A" (1982), a video compilation of several movie nude scenes which features her in outtakes from "Sweet Sugar" (topless) and "Terminal Island" (FFN). This video was available on DVD and may still be found on e-Bay. I do not recommend the DVD because it is an obvious videotape copy and not a very good one at that.
I have a copy of the original VHS tape. When I find it, I'll try to post a clip or two of Phyllis. In the meantime, here are a couple of scans from the "Terminal Island" outtakes (credit to the originator):
