    Looking good Vinny! Wouldn't it be nice if the physical build could be as fast as the virtual build

    .The Audi A6 Steering Column and the Sketchup version below.
    .
    .The Column in the car



    I've Started working on the back of the car, I have to decide whether to have the radiators up front (1997 version) or in the quarter panels (1998 version). There are 2 intercoolers that also have to squeeze in there. The cooler in the pic below appears to be an engine oil cooler.

    Getting the Camaro Steering Rack located in the front cradle tonight. The assortment of chassis tabs I had purchased are being put to use here, they provided a perfect standoff for the rack mounting. Highlighted in Red are the gussets I will add to connect the cross bar to the cradle sides.

    Working on widening the front suspension cradle the necessary 3.125" (79.37mm) to line up with the 99 Camaro steering rack geometry. The green section is the added width I'll be welding in place on the 3 cross beams on the cradle.

    The cut lines are marked in silver paint pen in the image below, which also shows the 99 Camaro rack above and the 85 Corvette Rack below. I needed the steering coupler section along with the pressure and return line fittings for the Camaro rack, fortunately these all swapped over from the Corvette unit even with a 15 year difference between the two. I'll also re-use the Corvette outer tie rods end as they have a taper unique to that car and will fit the Covette knuckles I'm using. And both Camaro and Corvette share the common 14mm x 1.5 threaded ends. Good thing I wrote all this down !.

    The SketchUp image with the blue vertical line represents the plane that the 3 points are aligned in: the upper and lower suspension pivot points and the inner tie rod's pivot point (pink). When these 3 are in line with each other, Bumpsteer should be eliminated

    Thanks for following, Vin

    True Don, and that was the outcome after sorting through a mountain of steering racks today. The majority of the racks were the rear steer variety common on FWD cars and trucks . I took home the camaro rack I had previously measured , it was still on the table where I had left it . There is no need for the inner extensions pictured above with this rack, it will accept the corvette outer tie rods . I just need to add 1/2 wheel spacers behind each front wheel. This should put the width where its needed, along with widening the cradle 3.

    Vinny;

    You can always end up with a 1/2" spacer as well if you can't find anything just right. Do the same as the pic above and just drill until you measure 1/2" from end of inside hole and end of outside thread and you should be OK? Need a lathe to do it but it could work as a plan B?

    Good luck with the search.

    Went to the wrecking yard Thursday afternoon for look at a 99 camaro rack, I'm chasing a front steering rack that measures 30" across to where the inner tie rods pivot. The Camaro rack was 29". Funny thing is I came up with a measuring formula on the computer that uses photos of racks and their inner tie rod lengths. I had the camaro rack at 29" before I actually measured one. When I mentioned I wouldn't be taking the camaro rack home because its the wrong size, the Yard Manager invited me to come back when I had more time and measure the assortment of racks they have on hand. I plan on going there tomorrow with a helpful printout of a "Rack Spotters Guide" I found online, it identifies the several common racks and what vehicle manufacturers' used them: TRW, Saginaw, Ford etc.

    Thanks Blooz, I am glad there are other eyes following this because in the mix of trying to think of everything, I can miss something along the way, so when you guys post its a great help. The mustang rack measures out to +2 (pivot to pivot ) over what I have now, adding 2 extensions makes it too long (+6). The 99-2004 Camaro rack looks to be 3.25 wider (pivot to pivot) than my current set up. Its close to the 4 Im after and no extensions needed. My local Wrecker shows both racks in stock. I may go there with a tape measure . Thanks for following , -Vin

    That's a nifty part. I wrongly assumed from your earlier post that you were installing the extensions between the inner and outer pivot points. What you're proposing will work just fine.

    Thanks to everybody here lending a hand, I greatly appreciate it. Here are the 2" extensions I mentioned a few posts ago. The illustration shows how they move the inner rod's pivot point outward.

    Using a pair of these and widening the cradle looks like the best option right now.
    .
    Also, along with this is swapping in a late model rack, the 97-2004 Mustang is on the top of the list right now. Finding a front-steer rack is not easy these days. It has the correct thread on the inner rods to fit the extensions, it will also will thread onto the Corvette outer tie rods which need to be re-used. GM came up with a oddball taper at the knuckle that only Vettes use on the outer end. Gheeze I hate GM sometimes.

    My local Wrecking Yard has a Mustang rack I can play with.
