    Your using a metric ruler on an American car? Major fail.

    It's actually not the cars. The fibreglass stuff is generally a lot of work to get good. I'm actually surprised it had holes drilled in it.

    Those hood hinges are porn.

      Amusingly, I posted on the B-Body Mopar facebook group to see if anyone else had had similar issues. The main response was "Whats a millimeter? there is something wrong with your ruler". Fuckwits.

          Lol, on the Bangshift forum there's a guy building a Corvette C3. The complete widebody kit he got for it from a supposedly well regarded supplier, not Ecklers, is beyond bad. He's actually had to reshape one of the wheel openings so his wheel is centered. And that's after he made sure everything, chassis, body tub and front end, was actually square. His latest drama is the L88 hood from the same company is too long!

            Great results!

            The PS pump, I believe I have a brand new one IF it is the same as a 5.7 pump.

              Too late! Bought a GM type 2 pump to adapt / mount up. Should make life easier as the pump pressures are better for my steering box.

                Time to update I suppose!!
                Been sorting some niggling issues to get this on the road. The factory power steering pump has been giving me grief since day-dot. It has an integrated reservoir and leaks like a bitch. Thought it was the pressure side fitting (which I ended up braising up) but it was the res the whole time. Cunt of a thing. It also ran dry at some point so it was shagged anyway. It also runs a shit-tin of pressure (like 1600psi) which is technically too much for my steering box.
                Logical solution - GM type 2 pump.
                So fuckit, I bought a pump, and what the interwebs told me was an appropriate pump pulley. Funnily enough the 3-lug bolt pattern on the pump is nearly identical to the Mopar pump, but the offset on the pulley and width of the pump are a long way off.
                Here is said pump. It also comes pre-installed with AN fittings so I didnt have to fuck about with weird mopar shit. Thank christ.


                Pressed the pulley on to see how big I needed to make the mounting bracket. Low and behold it came in at exactly 12mm. I got a couple of 6mm plate steel pieces to tig together:


                Simplistically speaking, the plate bolts straight to the head in place of the factory pump, so I used some countersink bolt heads to avoid interference and drilled to suit. I then tapped the bracket with an M8 tap to take the pump bolts:


                Worked like a fucking gem, and doesnt hit anything. It's good when you actually plan something and then take the time to execute properly...


                The only change was I had to get a new serpentine belt as the new pump has a bigger pulley. Easy.
                I bought an Aeroflow knockoff alloy res off ebay for cheaps. It is literally identical to the aeroflow deal, just no stickers and about half the price.
                So the setup is 6AN pressure side out from the pump into the steering box. 6AN return from the box to the reservoir. 8AN return from the reservoir to the pump.


                I have not tested this setup yet, so heres hoping I got the alignment right. Technically it puts out around 1000psi which is better for my setup.

                The other niggling issue was an intermittent TPS problem. It would randomly stop working and through weird shit values at the haltech, and sometimes the car would try to stall. I used a shitty aftermarket TPS rather than an OEM one. The TPS itself is some weird shit off a dodge Durango v6 or something... I think one day I will replace the throttle body with an LS style 90mm job and make an adaptor...
                I also had no proper plug for the TPS, so we did some dodgy shit with epoxy which probably didnt help. Anyway, bought a new OEM TPS, and found a plug on ebay as well. Once the plug gets here, we are back in business... Hopefully this week. Then I can take it for a proper spin!

                  Got a metal ruler?

                  Use the edge to align to your crank and whatever that pulley I see at the top is. You'll see pretty quickly how far out you are, use washers or spacers to adjust.

                  Those pumps are pretty good, you'll be happy with the fucking around to get it working.
