MG TD TF 1500 - Need TF tub measurement

If anyone has a TF tub open I need a measurement door frame to door frame as in the picture:

Another measurement I'd like to compare is the wood thickness as in this picture:

Hello, My body tub measures 47.5" across at that point (above the seam where the rear quarter meets the sill panel). I am not sure exactly where the other point you want measured is.
Max Irvine

Hi JE, my tub measures 47 1/4" acroos the same point as Max. Maybe if you take a wider shot we can see where the second point is required.

Thanks Max and DJ,

The other question was the thickness of the wood but since your tubs are close to mine I have another question:

What do you measure between the brackets as shown in this picture? I'm replacing my wheel wells and mine had shims between the wheel wells and the angle iron brackets which certainly don't belong.

The photo loaded upside down; my photoshop has crashed and I have nothing to rotate it with, sorry.

JE, luckily being on the other side of the world your photo appeared right way up! (just kidding)
The nearest I can measure is 18 1/2" from the wheel well to the centre line of the tub.
Hope this helps.Don TF 4887

Thanks DJ,

Does the print show upside down? :-)

I wasn't actually looking for the center line measurement, that's just the way my son was holding the tape. If my adobe wasn't crashed I'd mark up the photo to show exactly what I'm looking for.

There's something funny about the way the tub is assembled and I'm trying to figure it out. Angle iron to angle iron is what I'm looking for.

Jim,

Inside the irons halfway up the diff ramp is 33.5 inches. this is the same at the front and rear of the horizontal diff floor so there is no taper of the opening. this gives 36 inches outside the irons/inside the wheel wells.
I took the diff floor out to get these measurements, it was only sitting in there I haven't screwed it in permanently yet.

I did take the first measurement from under the car. The odd thing is I measured from the centre top hole of the transmission tunnel mounting point captive nut on the driver's side to the inner point of the iron and it was 17", on the passenger side the measurement was 16.5".

I pulled my tub completely apart to replace a lot of the timbers and this is how it went together. I don't know what the dimensions were to begin with but everything seems to fit well now. Good panel fit and doors fit and close very well.

I went to the 60th birthday gathering that Matthew mentioned in another thread to take a good look at fits on the 26 cars there and mine was as good as any.

Unless you are way out with your sizes you should be able to achieve a good result.

Jim, I agree with Max, mine also measures 36" outside to outside of the angle iron.

Jim,
The distance between the irons will be set by the cross brace when you put it in place. I assume you are re-using the original brace with the original holes that go through the irons.
Max Irvine

Thanks again guys.

I went to replace the wheel wells as the PO had built a repair out of sheet metal and riveted it in on both sides with brass brake rivets. When I took it apart I found 1/4" Masonite shims between the wheel wells and the irons also between the cross brace and the wheel wells and cross brace and irons.

When I went to install the first wheel well the holes didn't line up. I then noticed that the angle iron had a weld in it where there was no reason to be. The other side has been replaced and welded in in the same place.

I began to get concerned with alignment so I lowered the body back on to the frame. That's when I found the rearmost bolts didn't really align. On a hunch I cut the weld on the iron and a 1/4" gap sprung open, the body mount bolt dropped right in, and the holes on the new wheel well aligned! I'm going to cut the other side as well.

This doesn't completely explain the shim. When I bolt the wheel wells to the irons I have to flex the rear quarter in fairly hard to get it to fit. That may be the result of the repair that's at the bottom. I cut the top flange of the cross brace to get it out of the assembled tub. That let it flex enough to remove and I can simply weld it up and grind it for an invisible seam on assembly.

I still don't understand the shims between the wheel wells and cross brace but at least now I know the width of the car has not been altered.

Jim,
My wheel wells don't sit nicely against the irons either. I had to pull them up with the screws. I am not all that happy with that but I will just have to live with it.
