Series 2A(?) swivel hub nuts/bolts/studs

I'm rebuilding the swivel hubs on my 1969 Series 2A - new seals, gaskets, retainer, cleaning up the housing etc.

I made a bit of a mess of the nuts on the studs holding the steering arm bracket in place so I ordered new bolts for the swivel pin on top, and new studs and nuts for the underside.

The bolts, nuts, and studs, when they arrived were too small. I ordered by part number using my 2A parts catalogue. The parts catalogue says they're 3/8, and that's what the bags said when the bits arrived. I tried from Bearmach and Craddocks - both sent me 3/8, which are too small..

The attached pictures show the original larger bolt heads in the swivel pin, studs, and nuts, compared with the new ones arrived in the post. ((also note the slightly different moulding of the old swivel pin and the new one)).

Is it possible my land has an earlier or later axle on the front? Were they slightly different in that they used smaller bolts/studs etc. on the pin and steering arm bracket?

Any thoughts?

This is the same case both sides, the bolts and studs and nuts on the land rover are larger than what's being sent to me when ordered by part number from my 2A catalogue.. it's not just one side that's different in this way.

Late model 2A's [ head lamps in wing's ] like yours have parts that are common with series 3. At that time Land rover often introduced changes bit at a time.

You're right tottot. My brother's just sent me the part number for the swivel pin bolts as listed in his series 3 catalogue. craddocks describe that part number as Bolt Swivel Pin 1966 Onwards (237357).. the numbers are also different to the ones in my 2/2A catalogue for the studs and nuts on the underside. Looks like they beefed those fixings up around 1966.. fingers crossed these ones are right when I get some..

Ah the joy of ending up with enough wrong parts to build another landy

Also note that some of the studs used to attached the steering arm have a larger diameter plain length and act as dowels to locate the arms.

They should be right scotonthefen,I know my 63 has the smaller ones but could not remember when the change was.Cheers.

Wow its amazing what you find out when I did mine earlier this year 1970 2a I was lucky and didn't have a problem only the lock stop bolts was worn from the stops hitting on the bolts and I replaced the lock stop bolts from my spare nut and bolt box, very handy to no all this though
