    Trying to get rid of the last of my Roadster spares. All that's left now is an unused 4.11:1 diff for the 1.3 engined car and a steering rack of unknown condition but doesn't look too bad. Free to anyone who wants to collect them.

    Is that a Mk1 or Mk2 steering rack. Their mountings are different and they are not directly interchangeable.

    I have to admit that I don't know the difference between the Mk1 and Mk2. Some time ago I replaced the rack on my 1971 Marina based Roadster without realising that there were two variants. How can I tell the difference?

    for those who want to know the differences, somewhat inevitably, a document is available on Keepandshare. It’s free to access. I would rather it stand alone as most relevant answers are there too.
    As I intimated, it’s all down to the rack mounting difference and a change in length which is very odd considering that the chassis jigs did not change from one to the other. Very odd as the swivels at each end are identical.
    Either way, given that your rack is of indeterminate pedigree, it’s worth changing out the ubiquitous bush as a normal matter of good practice.

    Re: Steering Rack


    A quick way of telling is the MK2 rack has 2 different sized ends on it. The O/S is 35mm and the N/S is 29mm, whereas the MK1 is 29mm on both sides.

    Nice pic, I might borrow it and add it to my doc, along with the others, is it copyright?

    Do you have part numbers for the mounts, I’m pretty sure they would have been imperial sizes and not metric!

    Help yourself to the pic Steve, if you still want it. It's one I took during Brums rebuild.

    There 2 other differences the MK1 rack is 40.0" in length and the MK2 is 40.25" and the MK1 doesn't have the filler hole in the centre of the rack tube.

    Part numbers for fixtures on the MK2 ( mine is a MK2 so these are the only ones I have ) are:

    Rubber Rack Mount Pinion end 21H6799
    Rubber Rack Mount Support end 21H6800
    2 x clamps FAM1120
    2 x U-Bolts FAM1121
    4 X Nuts LNZ205
    4 x Washers WC108051

    Mine does have the hole in the centre of the rack tube so I guess its a Mk2. There is a number stamped on the pinion body which is 49 86R.
