As in old school 4 speed top loader? I’m not sure how being the handle is round at the base and has no holes in it. This is half of the infinite adjustment of the MGW shifter.
Gotcha. I forget any transmission that has the top access cover to build them is a top loader. I just think of the old Ford 4 speeds that came in the 60’s cars as top loaders. Shifting mechanism is entirely different.
I had a 3550 in my Mustang. The change in shifter position is not noticeable. The factory shifter on the TKX is a known problem area, so it's best to replace it anyway. The MGW shifter offers a large range of adjustment.
