Thanks mate, Dose that assembly include part of the floor pan aswell? If I cut out the floor pan aswell will I not have a problem with trying to stop the chassis from distorting/twisting after removing so much structural components.

 

Just peeled back some of the over sill in the corner and found some filler and a hole going through to the rear seats side pocket on the offside.

 

On closer inspection opening up the hole and looking down the inside of the sill (very small visibility) the inner sill only looks corroded at the corner at the rear and some at the front but further in it looks like its primed. If this is True if at all possible is it acceptable to remove the outer sill etc and just remove all the rust from the inner sill, patch any bad/missing material and then fit new outer sill or would you just replace the inner sill also.

 

I can feel a project coming on now. I originally wanted this mini to learn the ropes of mini ownership and just have a rough and ready run out for the weekends then maybe take on a full on restoration once I had learn a few things but if I cant have that then I might aswell just in the deep end and hope for the best. 

 

Thanks

The heelboard is the vertical section that the subframe bolts to, sit in the back of the car, where your heels are is the heelboard.

I think you are getting a bit confused. If you sit in the car your heels would be close to the cross member. The heelboard would be under your backside as its under the rear seat.

To be honest, I think your best bet will be to just do it all properly now, instead of trying to get it on the road, then worrying of all the crap when you come to restore it just so you could enjoy it for a year or what ever.

Basically, get proper stuck in :P enjoy! :lol:

Personally if it's not your daily driver I would remove the over or outer sill on the worst side that you suspect, with a grinder it'll only take you an hour or so if you have never done it before, then inspect what is behind, if you have over sills fittled you may find the original outer sill if not then you will reveal the inner sill or technically the floor (as there really isn't an inner sill it's actually a fold in the floor that helps create the box section, but easier to call it an inner sill)
I would then post up pics on here of each end and the middle so we can all help and advise you on which panels to buy and the best way of fitting them.
Remember take it slowly with the grinder so you only cut through the layer you wish to remove

Inner sill or really the floor

New inner sill and heel board end going on

Outer sill back on

Hopefully this allows you to see where best to cut to remover the outer sill, when I did this one for speed I cut along the underside seam where the doorstep and outer sill join with a grinder with a 1mm disc then due to having over sills fitted the oversill had been fully seam welded tl the floor so the easiest way was to slowly grind through the weld and peel it back

Hope this helps

I love the accuracy and depth of information on this forum! 

 

There are some truly fantastic knowledgeable people on here!

 

It looks like you're going to need to do a small repair to the inner wing too at the bottom.

 

Post some pics up when you've taken off the oversills (they are a bodgers best friend and a minis worst enemy)

I think the OP can understand I don't mean the fresh air behind your heels but the nearest vertical steel section to them, lol

If you have a look at the thread Wills Mini Special in the Prihects section you will see exactly what and where you need to do. This includes bracing etc.

Thanks for all the advice guys, hopefully get the mini round to the father inlaws garage and start cutting out the sill either later today or tomorrow. Unfortunately I work away from home and I'm away on wednesday for 6 weeks so it's going to feel like a long time before I get her sorted.

but that was my point, it isn't the nearest section, unless your legs have an extra joint and fold back under you! It could be very confusing for someone looking into it for the first time so they need clear explanations of which bit is which.

And make sure your subframe is solid. You can weld them, but not plate them anymore or it'll fail it's MOT.

Does this look like all the parts I need? Anything missing? I already have a left hand outer sill but its an over sill. Can you just cut back to the narrow size of should I buy a LH one aswell?

Yes you can, just mark the line where you want and cut with a bandsaw or thin disc in an angle grinder if you have a steady hand.

Well both times I included the word vertical, the first also had a link to the part which includes an exploded diagram in detail of that area. My car like the last four minis I've had have still only had one vertical panel behind your heels when sat in the back, :-D

think about sitting in the back of a mini- your feet go under the seat in front so the nearest vertical surface is the back face of the crossmember under the front seat. So 'where your heels are' is closer to the crossmember than the heelboard. Which is why I clarified it so the OP didn't get confused.
