A518 lock up conversion

As far as kits go, the only one I saw that is a good value is from PATC. I built my own kit very similar to is but I used adjustable pressure switches. If I remember I paid a bunch more than the PATC kit and I have a crappier vacuum switch. I see they sell adjustable pressure switches as well.

That's the kit I am looking to purchase. I haven't cheaper out on any parts used in my trans build, I'm just trying to get the proper parts but seems limited in my selection. I had my trans built for monster torque rating so I'm not going to,stop here. Pay now or pay later I have always been taught.
