The Browell bellhousing was probably one of the best purchases I have made. As Mr. Ames pointed out, you can have the window clocked anywhere. The hole for air gap measurement they will drill and tap it for a plug. The other added benefit, alignment was spot on with 2 different engines. You get what you pay for.

427FE,
If you are wanting to modify the bellhousing yourself, its been done. Others will tell you "Tech has never looked at my bellhousing certification date so have at it with modifications". That is up to you. For those with bellhousings without a window, its not uncommon that they drill a hole so a long allen socket will reach the adjuster. CW is a different can of worms. I fabricated offset wrenches and would put duct tape on the wrench to capture the hardware and reach through the fork window. It was a fishing expedition when I dropped aluminum nuts or bolts!

There are pictures and how people with fabrication skills added a window to their bellhousings on the internet.
