Default I am looking for info on harmonic balancer

So I have a 5.3 in my foxbody. I tapped the front cover for my oil return line, I put the -10 fitting on the lower corner on passenger side. I thought I would have enough room with the harmonic balancer but I'm wrong and they will hit each other.

My stock balancer is just under 7 3/4" across, I'm thinking an underdrive damper will solve my problem and give the clearence I need. I was going to purchase a SLP damper but I can't find any demensions on it.
Anyone have a clue of the diameter or preferabley a measurement of h ow wide it is for my application?

They advertise a 25% underdrive, correct?

5.8125" diameter is what I come up with from some quick math.

My SLP has a huge lip to retain the belt, but that should get you close. I'll get an actual measurement later.

I ran into that problem myself, this is a 25% underdrive damper.

The picture of the 25% under drive looks like it work in my set up. What is the measurement across the front from side to side? And dieter is all the way around correct? Maybe I asked for the wrong measurment in the beginning. I need to k ow total width of a 25% under drive pully/damper

Diameter is "side to side." My 6.25" is from one edge to the other on the front of the pulley.
