The field of enquiry for the shock towers is now narrowed to between MB 105904 and MB 127470

Ian,
I have what I belive is a jan 42 mb. No frame number present, but tub number 15187. That should put it in the 111xxx range. (I believe). It does have 2 toolbox hinges per door. So that would definately put it pre sn 118600(per jim kilbourne's chart http://home.ntelos.net/~kilbourn/WILLYS ... atures.htm).
I have the curved reinforcement for the shock support on my left rear. The right rear is missing.
I hope this sheds some light
Mark

Hello darth.

Thankyou for that valuable info. Can you please confirm that your frame has short reinforcement straps? If it does then it weould be almost certain that the frame is original to the body and then we can set off again with a narrower field to look in to. Searching for MB's between MB105904 to MB111XXX- re: curved rear shock mount- see pics on previous page

Maurice- i`ll get a pic of the rear of my early MB chassis soon and post it up for all to see the differences. Jim K- any news as to when the change actually would have occured to the rear gusset since MB 336178 has the change yet it wasnt meant to come in until MB 351XXX- 15000 off?

Does someone have a MB chassis around MB 300000 to see if this MB has the different rear gusset? If so theres another area to search for!

Thankyou all. Keep it coming!

Ian,
My frame is off being sandblasted at the moment. I should have it back by the end of this week. I'll check the straps and let you know.

As it is not certain that the change to type 2 suppression occurred at MB289001 and since frames may have continued to be supplied with the threaded bonding studs welded to the front crossmember, after the change to type 2, the best we can say is, that this change occurred at approximately MB 289001 or Dec 1943.

Your above photo of MB 336178 with the red arrow, highlights the vertical gusset I have been referring to, you can just make out the 1/2 moon cut out, under the shadow. I had expected that this frame would have not been modified, based on Jim K's info that the change occurred at MB 351XXX. However, it is now clear that this change/modification occurred prior to your MB 336178.

If you can photo your early frame in this region, we will see that this gusset has a straight rear edge and is not as long as the 1/2 moon cut out version on later frames.

Actually, the 1/2 moon cut out version extends further towards the rear crossmember and was designed to strengthen this area. It should also be noted that the 1/2 moon version uses two additional rivets on the top of the frame and this can be seen in you photo.

Regards

Maurice
Hi guys,
I may be able to help extend the picture a little as I have MB290463. It has type 2 suppression. It must be early as it lacks the ignition switch suppressor, identified by the screw hole in the dash.

I think (I'll have a look when I get home) it has the later, changed style of of rear spring hanger frame support by the rear crossmember. It does have the ground studs on the front crossmember.

Best regards

Hi Maurice and guys,
I have checked my MB and it does indeed have the half-moon cutout in the rear face of the gusset.

I also have MB 119955 ( Feb 42) Canadian contract , it also has short frame supports and early shocker mounts.

Scott,
MB 105231 should be a bit earlier than Jan 42. Did you mean 115231?

Thanks scott! By early (in reference to MB 119955) do you mean it has the flat bar shockabsorber mounts as these are the earlier ones as found on jeffs MB, or do you mean the later ones as found on my mb- 131175? with the rounded edges?

Thankyou Bill, Any and all info GREATLY helps to reinforce prior knowledge!

Jim, please keep us posted on the/your frame data.

Thanks Al! So now were looking for MB's earlier than MB290463 for the change in the rear spring hanger support. Jim, what was your source for the initial serial number- i think Nabholtz mentions something doesnt he? Could we be looking for 2 different changes? What do people with MB's after MB351XXX have in this region?

And slack me still hasnt gotten to my mates place to look at those chassis's in relation to the short/long straps, but now ive finished uni for the year :D , i`m sure to be able to get up there.

Cheers, and good to see this IMPORTANT topic hasnt completely died!
Ron/Moderators, Is there any way it can be made into a "STICKY" post again?

Hi Ian,
It would be interesting if we could nail down exactly when the radiator bond strap studs on the front crossmember were dropped from production too.
