Well... I can tell you that the front seats are in place.
They weren't really too difficult to get in. We bolted them in place using the existing captive bolt on the front inside edge (i.e. nearest the transmission tunnel). Then we two drilled new bolt holes on the sill sides - watch out for the brake cables though! There was no way to fit a fourth bolt, but the seats seem secure with three.
However, there were a couple of complications.
1. The seat belt fastenings had to be swapped from the old seats.
2. The bottom end of the seat belt is held in place by a bar whch bolts next to the sill. This was in the way, so we opted to shorten it and by cutting it and welding the two pieces together.
The seats I bought were electric and we found the easiest place to take a feed was from the center console cigarette lighter.
The rear seat is looking more awkward... The lower squab is fine, it wedges in place quite snugly. The back is going to cause a few headaches though.
This interior was out of a compact, so it has a split. It comes in four pieces - 2 side pieces that sit over the arches and the split seat. The seats are slightly taller, but we think we can position them in such a way that they don't rise up too far above the parcel shelf.
We are going to bolt them to the rear bulkhead. I'll give more details once it's done. The main problem will be the side pieces, which are a very different shape... They are going to need some 'modification' !
I'll take a few pictures tomorrow and post them up later in the week. It's looking pretty good already though.
