Got them fitted yesterday and theyr'e great.
They didn't go as flush as I thought and I had to trim the flanges slightly but this was fairly straightforward. I think I could have got them more flush if I had elongated the fwd bolt holes but they are so well made I didn't want to modify them too much.
They are a really good fit and no bodywork needed trimming at all. I just had to cut a notch in both front mud flaps and that was it!
I wet-assembled the front mounts with LPS (Corrosion preventer) and after drilling the rear mounts I wet assembled them (using M10 bolts and nyloc nuts) with etch primer.
All I could do with now is some skateboard, non-slip tape to stop people slipping if they use the sliders as steps!
I had soaked the sill bolts with 'plus gas' for days before but some of them still sheared as I removed them but I dont need them anymore so I don't care! I also had to use an 18" breaker bar to release the front mounts and thought they might shear but they survived.
I can definately recommend these sliders (From Richmond Shot Blasting or Rock-Slider) as they are very well made and fitted a treat. I did have to trim the flanges slightly but that is only so I could align them neatly. I didn't have to trim any bodywork at all and my photos show how neat a fit they are.
The only thing left for me to do is to matt black the edge of the floor pan that has been revealed by the sill removal and is visible between the bottom of the doors and the sliders.
There are loads of photos on my album and I have only added a few to this post so please feel free to look at the album.
Oh! I now have a pair of good condition sills that are free to anyone who wishes to collect them from Luton. They are used but OK.
