The rear tub will be removed at some point and the mid crossmember replaced when it is fitted to my current hardtop vehicle which does not have one. But I want to as much of the tub rebuild in situ before I remove it as possible.
what do you mean bend later? The middle floor currently site on a lip i assumed this was part of what is being replaced with this new panel as that has also disintegrated at both ends. drilling holes is no problem, I was planning on fitting bolt rather than screws anyway as that is what I have done with my front floor panels.
Ah if your rebuilding the tub fully first then moving you will be fine on the crossmember side.
But you will want to be careful on a few points as YRM work to land Rover tollerances.
the C pillar is a right pain in the arse on a CSW as there are 3 bits that come together between the mid crossmember, C post and Tub floor.
Corner repair pieces
if you repair on the current vehicle and then move it you could have issues with clearance on the corner pieces unless you make it very slightly smaller to be safe but you could end up with a bigger gap on new car between the front of the tub floor and the c post. you may get a better looking repair doing those on the new car/later.
Front of tub repair pieces
There is a re-enforcment strip that runs on the underside of the front of the tub. not fitted to the repair section (check with YRM may have changed). be careful on its placement relative to the c post bracket when fitting to the tub you dont want the holes for the c post to go through/or close to the middle of the re-enforcement otherwise you wont be able to bolt it down properly.
Seat brackets front of tub
save the seat brackets they are hard to order i ended up getting Exmore trim seats as couldn’t wait any more, to get new seat brackets for the older style low/folding seats was on back order for 6 months and couldn’t get an eta in all that time.
When i did mine i watched the land rover assembly video on youtube and built mine up in the same way, i got a real appreciation for land rovers line workers as nothing ever lines up.
the replacement piece wont have holes in the lip for floor (i don’t think, YRM may have changed)
By bend was more for if you changed mid crossmember with tub in situ, you have to bend the front of the tub up to get crossmember in (YRM do a kit where the crossmember is in pieces so you can slide in) but probably not needed for what your doing. LR workshop have a video of fitting that will show if anyone needs.
