Studs

[bwaminispeed]

Austins were mostly bolts, Morrises were mostly studs.....but, there was some crossover of that......nothing to do with wet or dry......

Dry subframes have a 3/8 Unf hole with stepped down to 5/16 studs.
Hydro subframes have 5/16 Unf holes with 5/16 bolts.
Later subframes of course had the big single bolt.

So you are saying Austins had bolts with dry subframes?
So they had 3/8 bolts?
Can you provide evidence of this please?
I have worked on a number of Mk1 Austin Minis and own a 64 Austin van. They have all had studs dry or bolts wet.
I have never seen a 3/8 bolt screwed into a dry subframe, but I am willing to see evidence on it happening.

Got me thinking.........I have seen 3/8 " bolts with a locktab on dry subframes.
The bolts had a wide groove machined on the shank below the head.
Somebody on here must have a picture.

This would be for UK built cars, Longbridge (Austin) used bolts, Cowley (Morris) used studs.....

Probably different for OZ built cars......

These are some bolts and studs I have found. Bolt 3/8 unf

850man , Evidence , take a look at the bolts with 3/8 die on , you learn everyday , don't forgot the UK made BMC mini first and your just got the left overs Austin bolts , morris studs .

My late 65 Morris hydro has studs.

[Andrew1967]

60 Morris has studs
64 Austin has bolts
65 Morris Cooper S has bolts, but guess Cooper / S will as they were all built at Longbridge.
68 Morris Cooper has bolts .. as above

Yes, Australian cars are unique but we do have a number of UK built cars here. It seems lots of them have been imported from the UK over the years and in recent times, Vans, Pickups and Elfs/Hornets are coming across from New Zealand.

850man,
To add one more data point, my Nov 63 Austin has (original I believe) studs.

Was it the dry or hydro car that had the spacer between the subframe tower and crossmember?

[Dr.Mabo]

The dry subframes need the spacers

As Dr.Mabo says dry , Minispares stock them if you need any.

Cant get to my 66 at the moment but all these 64 ones have bolts Feb Austin, October Morris and November Austin. First is dry, latter wet.

Early CKD Austrlian assembled Morris cars used the bolts shown here. They also used the early lock tabs shown. I own 2 Morris cars with these one is a 1960 CKD 850 and the other a 1962 Cooper. Australian CKD assembled cars used all of the UK supplied mechanical and body parts. Paint and trim was Australian based.
Later subframes (circa 1963) were supplied with studs and a different lock tab which had a grommet in the centre allowing access for the cone compressor.

Hi Bruce,
Yes I am well aware of what our Aussie CKD cars came with, having owned a number of them myself.
The Original post asked what a 1964 car with dry subframes would of had, without specifying what make the car was, so studs would be the logical choice. Or bolts. Either will work.
