TR2/3/3A TR3 floor / frame mounting point question

[tdskip]

Hi guys - I was picking at the TR3a today (yes, shocking, I know) and noticed the DPO kinda of made a mess of the body to frame mounting.

How should these look? How would you recommend addressing this?

Thanks!

Are we looking at the ends of cut-off bolts? The body mount doesn't look that bad to me, but I am having trouble seeing what's going on with the bolt holes.

If the pad is removed, do the threaded holes in the frame extension line up with the bracket holes on the sill? I take it you are doing the floors while the tub is mounted. You might weld a thin plate over the sill between the floor to pretty it up since the stamping of the floor pan is not a critical contact. The bolts hold it all together. That center rust hole is where they touch. On the whole I might just clean it and paint it *. Really, with new floors it is not going anywhere. The bad thing I think would be if the frame extensions are rotted at their tube supports.

* these are just the thoughts of another future DPO

No - they don't, which is the concern as they should.

CJD - these were taken looking down at the mounting point from above. The floor to body mounting bolts should screw in there there (I believe).

Is there a pad between the top metal part of the sill and the frame? Might that be what is under the holes? I've not take the body off one of these yet, so forgive the question.

Oh. I see a little of your floor is missing. That section of the sill should have 4 holes, but the floor will only have 2 holes that align to the threaded holes in the out rigger of the frame. If you push that little pad around that is sitting between the sill and the rigger, you should find the holes -hopefully without broken bolts in them.

The tub should move around enough to align the holes.

There are pads. That's why I say I can't see what we're looking at. It could be the rubber pads are just slid so their holes do not line up with the holes in the mounting tab. With the floors removed, the body will have some ability to twist, so that can also account for a mis-alignment.

It does all need to line up so you are satisfied before the floor pans are even tacked into place.

Hi John - but the bolts have to pass thought the four openings, right?

 

[CJD]

Only two on each mount.

Just to add to the points made by all, these are a couple of pictures of a scrap tub I was cutting up last year. Note the distance between the original floor and the sill bracket. The floor contour reinforcement is about 5/8 inch deep. There are only pads under the sill bracket, the two layers of metal above just sandwich together.

Hi guys - thanks for the coaching here.

So in the picture above the floor mounts to that sill structure, correct?

If so, then as suggested, I have some packing/mount materials from the old floors sitting on top of that in my pictures, correct?

Do I just cut that off/back to the sill structure in the picture above?

Thanks, and sorry for being denser than usual on this (insert joke here:______)

Like I said, I am having trouble from your pics seeing exactly what you've got going on. It appears the rubber may be stuck underneath and blocking the holes on the mounting plate...but it's really hard to tell without poking at it with a screwdriver or something. It also kinda looks like maybe seam filler could have gotten all over it...like a putty filler.

I think you'll have to clean it up and see what is left when you are done...

Hi John - will do that this weekend and post (hopefully) better pictures.

Thanks

I agree as well that it's tough to tell from the pictures. Almost looks like someone's attempt to repair the mounting plates.

Got bored, so sat here looking over the photos.

I am guessing that some PO squirted seam filler between the floor pan and the inner sill body mounts. It looks like the filler spread out all over the mount. But, it does not look like the mount is rusted at all, which is great. I even think you can see the rubber pads underneath, just off center. It appears the mounting bolts were never installed after the seam filler was added. Perhaps to stop the rattle from not having the bolts in??

Anyway, it will be interesting to see what you find when you clean off all the goop.
