anyone know what plugs/bolt sizes are needed to plug up the holes on the steering assembly after removing the lines? i don't have access to a welder and im not sure if i want to trust jb weld over thousands of miles + vibration.

It doesn't work for everyone.

I tried the Gotham kit - it lasted 20 miles and I put the power steering back in.

It may have been OK for street or track use, but I autox my car, and there was no way it would have worked on a tight course.

I took it for a drive on 245/45/16 Toyo T1S on stock wheels, on a twisty mountain road. The steering effort was just too great.

While probably OK for street use, it would have cost time in slaloms or tight corners, as it would be too slow to turn.

Oh, and that autox tires are 285/30/18 Kumho V710's - very sticky - manual steering was out of the question.

BTW, someone mentioned sourcing the parts yourself and saving some money.
Not only will you not save any money, you will spend more, plus a lot of time.

I replaced the fitting at one end of the Gotham kit with a 90 degree elbow, as I needed the clearance under the Oil thermostat.

It took a lot of time to locate the right part, and just that one fitting was $15.

i had a small writeup about this not too long ago when i did this and my ac removal at the same time. i also had the bolt sizes in that thread too. just search through my previous posts (i would do it for you but i have to get off quick) the jb weld will be perfectly fine (though i used permatex cold weld) because your only using it to seal dust/ dirt from getting inside your rack. i will try in the next few days to post all the pics and my complete write up on de-powering your rack but really the jbweld works perfectly as it certainly will not come out or break up with vibration if you use as directed.

I've been driving my girlfriends Peugeot which has no PS, at first I thought it was hard work but after a few hours you get used to it. After reading this thread and removing my AC I'm really tempted to remove the PS from my FD, it'd certainly help with its diet.
