I had to take my Electra Glide Custom to the HD service to get the PA state inspection. When I pulled it out of the garage an it was next to the Freewheeler, I could not help but notice the similarity in the seat dimensions. When I returned I measured both and then proceeded to remove both seats and swap them.
Perfect fit.
I actually like the Mustang wide vintage better than the Tallboy and on the EG the Tallboy is also very comfortable and allows me to sit even further back than the mustang did. I love the look. Since Freewheeler parts are tough to fine the manufacturers are way behind in IDing interchangeable parts, I thought I'd post pics her so that everyone would be aware of the fact that the EG (and I would expect the Street Glide) seats are an option.
