110 Rear tub comparison CSW verses HT

I have a 110 Hard Top getting a new chassis shortly.

I want to explore the idea of grafting in a CSW rear floor to give a footwell for some forward-facing rear seats where the long wheel boxes currently sit.

I am imagining cutting the HT wheelboxes ahead of the rear wheels and getting a used CSW rear tub, cutting out enough of the floor section to drop in. The existing hard-top exterior body will remain. Since the HT rear tub will be off the car, this seems like a small amount of additional work.

I was trying to find an exploded view of the CSW rear tub and rear passenger floor section to get a feel of whether I need the tub or just the central CSW floor section, but nothing shows it clearly. I understand there is an additional cross-member in the CSW which I would have to get.

I know how you all like to give constructive criticism and so you are welcome to do that. This seems do-able so perhaps I need a lesson in reality.

Hi tim.
Im a bit of a novice Im afraid, but working through a CSW refurb. As part of which I replaced the rear floor with one salvaged from a written off CSW.

There is a U channel member that runs under the front part of the main floor panel, just in front of where the wheel arches drop. It bolts to the angle supports on the cill members.

The second row seat box was shot on mine - it sits in front of the wheel so gets shotblasted. I had a local metal factor bend some 2mm Al for me. Ive been fitting it last weekend.

These photos may be of use to you. If you need any measurements, I may be able to help.

Thanks for the pictures that's perfect! Is this project published somewhere on here?

In the first picture, what is the unpainted part where the seatbelt anchors are lying?

Where does the cross-member (not present on the hard-top) go? Is that the part visible under the leading edge of the rear tub floor in the first picture?

What is the new L shaped piece in the last picture? The 2nd row seat-box? Doesn't look like a box! How is it attached?

I have seen body-mount brackets on ebay, where do they go? Are they pictured?

Looks like I need the floor sections of front 12 inches of a CSW tub (including the sloping section with the stepped brackets), plus the seat-box and extra cross-member. Then the flat floor of course. Then delete the hard-top bulkhead behind the front seats (with a bulkhead replacement bar).

Ive not published the project on here yet. Might do it at the end if there's enough interest.

The unpainted part is actually a reinforcing/capping piece of aluminium added by the previous owner to cover some major corrosion in the Al floor panel. That point in the floor is where a steel spigot joins the Al floor to the steel chassis (and provides belt anchor points) and so it corrodes something terrible. The floor is one large T piece - basically the black bit in the later photos. It is riveted to the U channel member at the front under the T.

You cant see the front T section or the U member that sits underneath it in the original picture as I cut it all out. The U member bolts to the angle support on each cill where the T section goes. EDIT: top photo, look at the bottom left hand corner to the small steel ledge with two holes in it, then across to the other side half way up the angle cill member where there is the other steel shelf with holes in - member bolts there.

The new section is the step drop from the rear floor height, down for the second row foot well. Its actually "S" shaped - the top fold is just long enough (1.5") to sit riveted and sandwiched under the rear floor panel but above the leading ends of the floor strengthening members that run front to back from that step to the rear door. Three of them.

The second row foot well has a single floor panel that sits on the rear lip of the front seat box and the bottom forward fold in that rear step piece.

You may do better getting some sheet Al folded up unless you can lay your hands on a salvaged rear floor and second row floor panel cheaply.

EDIT: Here we go. Found a pic of the underside of the rear floor, into which I slot the formed box step between the strenghteing members and the underside of the leading edge of the floor plate. The blue colouring is the Al sheet plastic wrap. YOu can also see a pair of formed caps to tidy up the ends of the step.

this may be of some help... its the set showing the strip n rebuild so far of my 110 csw, may help

although later on I have cut into the rear arches to fit the classic 60/40 bench which prob will be of no interest...

cheers steve

This is very helpful guys!

DSC_3316 shows the body-mount brackets and where they go which is good to see

It will take a while to absorb all the information. I am going to look at a CSW at the weekend see if I can lift the carpets - assuming it has some.
