Harley Twin Cam 5-Speed Transmission Dipstick & Filler Plug – Softail, Dyna, Touring (1987-2006)

Here’s a solid used part for your Harley build: a chrome transmission filler plug with dipstick, compatible with Twin Cam Touring, Softail, Dyna, and FXR models from 1987 up through 2006.

The part number is 37075-87, OEM fit.

It’s definitely got some patina—a bit dirty with some marks from storage and use, but structurally it’s in good shape.

The chrome still looks decent, and it’ll thread right in like it should.

The photos are stock images, but the one you get will be in similar condition: used, but ready to bolt on.

If you’re piecing together a project or just need a replacement for your left-side filler, this is a budget-friendly way to go.

Made in the USA, so you know it’s quality.

Don’t expect showroom shine, but expect it to work.
