TH350 filters question

[bhabben]

Folks,
I serviced the TH350 in my '75 Skylark and have a question which filter it is supposed to use. When I got the car, I swore it had the bottom-feed style (AC-TF213, Fr-FT1033A, etc.). After having been rebuilt, I opened it up to change the fluid and filter and it had the top-feed style installed (AC-PF171,Fr-FT1021, etc.). The book calls for the bottom feed style. Is the topfeed style filter a better design and a common retrofit? Which should I use?
Thanks,
Brett

TH350 filter

I always use the top feeder filter with plastic screen. I have never had a problem with them tearing or plugging.
