Sway bar for a 69 XR7 with a 390

What is the best size for the front sway bar on a 69 XR7? I put a 1" in and now I cannot get my oil filter on. Any thoughts?

I had the same problem on my 68. I ended up using a stock 7/8” GT sway bar.

Many of the sway bars you buy from the aftermarket are made to fit Windsor or Cleveland small blocks. Like the one you bought.
