I am going to go ahead and depower my rack in my 89 GTU. In the past I have done this the shitty way removed the lines, turned it back and fourth a few times to get fluid out and capped it.

This time Im going to take everything apart remove the unneeded seal(s), weld the quill and grease everything back up.

My question is regarding the fittings that are generally there for power steering lines. I have seen some people remove these fittings and thier bosses and weld and smooth the surfaces which looks quite nice. Also I have seen people take the fittings off and weld them shut, this seems "ok". What I am wanting to know is if anyone has sourced any nice OEM looking plugs that could be used? Does anyone know the thread sizes of these holes?

Another thought I have it to put grease fittings in at least a couple of the holes? Any thoughts on this?

 

take the rack to a hydraulic shop and they will have an assortment of cool looking plugs to choose from. black, brass etc. or at the very least they can tell you exactly what you need and you can order some cool anodized plugs from wherever

 

I would weld up the ports and smooth 'em off.
Fast, cheap and easy.

 

They are probably British straight pipe threads. I think they actually call them Parallel British pipe threads. Metric pipe threads are British pipe threads. Go figure. Most hydraulic threads are straight versions of standard taper pipe.

Anyways, a cap is sure to be found at a hydraulic shop or a good online source.

 

I went ahead and welded the fittings shut, ground them smooth and painted them. They turned out pretty good. I think later I will add grease fittings once I have the engine in and can see where I will have access. Welding the holes in the aluminum definitely looks nice but currently I don't have the capability to weld aluminum.
