I'm thinking sometimes paying labour may be worthwhile, not worth pressing on with this? Stubborn bits on this 2014 car - as I mentioned on another post but feeling a little defeated which isn't usually me with cars:

Top Bolt siezed coming off ARB drop link, probably easier cutting the drop links off now as the small spline is spinning now anyway/ not enough traction to force the nut free although its moved some.

Even bottom drop link to arb nuts pretty tight, wouldn't crack normally with reasonable force, feels like it will need a long breaker bar just to crack that off :D Then I wonder if that could have the same issue.

The lower pinch splined bolt is pretty solid rusted in - even though the nut loosened off easy enough so can get that off
Tried a short while anti clockwise with electric powered impact wrench from spline side or lump hammering out from the nut side and its going nowhere....probably needing heat?

Just losing will to live with it personally and thinking paying £100+ for my local man to faff about with it isn't a bad idea and I can afford it, especially with the weather?
But will have to wait a month or so for their booking it in though should not need to do to much driving in the meanwhile....just disappointing as was hoping to get some improvement on the car this week....:(

Thanks for like Adam F.....
I think on consensus its being angle grinded off, I ordered a Febi one with next day only about 15 quid amazon if its hopefully the right one
Garage MOT'ing today and they might do this for me and think will get them to change the leg as mentioned the pinch bolt probably swelled up in there.

I did a shock change this morning and had same problem with seized pinch bolt, smacking it with a hammer didn't do anything ended up heating up with blow torch and using impact driver on the torx end manage it get it free.

Yeah I didn't put heat on it but balancing the idea that cost of labour isn't so much probably only be about £100 so my local garage is going to do it if its that much hassle
That is absolutely grotty no wonder they seize ! Fabias don't seem anything like as bad, probably not as tight fitting or something.

I looked at my garages original costs for other side when it snapped and I had company and needed it done more urgentloy - which seemed high but mostly due to parts.
I'm supplying those now so will be all labour.
They are all like nearly new parts I bought (boxed new but unused) opportunistically when looking for parts on ebay, so have saved quite a bit already.

Sachs OEM front spring, monroe shock ( match what he obtained for the other side not my personal choice), top mount and bolt set, cost each something like £40, 40, 60 and 15
( plus per garage having to cut off and replace the drop link that was another 15)
Total of £170 in parts so paid quite a bit more from the garage, labour hence is the smallest part of the costs ! For the hassle as above quite happy to let them have it.

On next job - still might brave on doing the clutch having done the wifes citigo so know roughly how to do..I suppose less likely to have bolts like this to face
Clutch been feeling like its more at the tail end of its life though still pretty driveable moderately its just the tuning is a bit aggressive so if you are greedy I'm starting to feel slippage I've never felt before. The power does account for the 13.89 second quarter mile at Pod first time I ever drove a car there at least though :D
