About Supa Ninja post-

It's a standard 1303 75' rack, reconditioned and modificated in the points of fixing the absorber and the lock stops. The car is a 1973 1303 (with steering box). For economy reasons, the rack is exactly the same as the Audi 80 or VW Passat (same lenght, diameter, working direction order, fixing of the steering arms) less the fixing points themselfs (which very easily can be converted to fit) and the drive axle fixing channels (requires a slight different shaft, also easily obtainable). Didn't check the drive ratio though between the to


About Steve C post-

The procedure for me was as you mention on your post. Two points though to mark: My car had already the depression on the body AND the holes WITH threads for the fixing exactly below the cross brace that has to be removed, so it was relatively easy for me to do it. BUT in a second 1303 car (probably with 1302 chassis?) none of the above were present so I had to fabricate them. The nuts worked the same way as you and the chassis job went in the second way you mention: First I cut the entire spare wheel well, I cut the chassis and rewelded (with interior strenghtening) to fabricate the depression and then I rewelded the well. So those minor?? details in my opinion should be considered before starting anything. About the lock stops, on the passenger side is easily obtainable as there is a cap of about 20mm which can be drilled and tapped. For the driver side the cap is made of thin tin, so I had to replace it also with a thicker cap to be possible to tap it to accept threads. The locks are 10mm allen bolts without head. So the only way to do it right is to have the rack dismantled.

As a general feeling, the steering is very strict (not any suspision of dead movement) very fast from side to side (don;t remember exactly but for sure less turns comp. with the box) and very light on the still turning: with a 225 tyre A LOT easier than a good box with 165 tyre. No info though on the street because the car isn't running yet. Hope to find out soon!

I'm using the rack from an Audi 4000 / VW Fox / VW Quantum.

It has center-mounted rack ends, end-mounted input and is available with power steering if I get old and feeble!

Where would one go about buying a r&p? I'm in the middle of nowhere canada and not a lot of super beetles around.

Hello all

vwbao, if you want I could send you some photos, to see which are the differences between the stock one and the Audi one. Actually I couldn't tell you for sure which model exactly is but its something about the years 78-80. Just give me a mail address to send you the pics and you could go after it with the pics in hand.

About what dorigtt said, if what he describes is the smaller aluminum bodied assembly (from the European VW polo), I think you could go this way much easier, because is a lot smaller and thus easier to fix it. Actually there is a German company that has this conversion (with TUV included) ready as a bolt on kit, as soon as I find the link I will post it
