Hello

Can someone help me to ID the steering rack on the right of this photo? It's supposed to be a RHD TR4A rack, but it could be a later one. The one on the left is a late TR4 LHD rack.

Thanks for your help.

Myles

Myles-

I have an LHD TR4a rack up in the attic - I can visually see if the casting is similar if you need the information, is that what you are interested in? I thought from the factory drawings you would only see a minor difference in the track rod end lengths - is it more significant than that?

Yes - I was expecting that the casting was going to be the same as my current LHD rack. This one is different and I was wondering if that is because it is a TR6 rack, spitfire rack or something else. I know that the TR4A, TR6 and spitfire racks are all interchangeable. So, if you can check the casting that would be great.

Thanks

Myles-

Casting looks the same to me as what you have - I roughly measured between 3 to 3.5 full turns lock to lock on the rack.

The lettering on the top of the casting is a British Patent number which is 766 something (I can't make the rest out). Also on this rack the number 12A71H is stamped on the pinion housing and the number 5L03998 is cast on the underside of the rack. Nothing so useful as a part number though!

Randy, thanks for the photo...looks like this rack has been positivley ID'd as a 4A rack...
