Buy 2 Bosch 21in Superplus wiper blades - as per the photo attached "Donor Blade" - you need 2 as there are just 2 parts required on a blade and you need 3!!!!

Remove the actual blade from the wiper as per "wiper Disassembled"

Seperate the two smaller parts that grip the blade as per "Part required"

Now -- the tricky bit --carefully open out the centre of the part required so as both sides are parallel and then CAREFULLY drill the middle of the part so as to accept a 2.5mm bolt.

Take the original Morgan wiper blade - "original blade" and punch out the rivet holding the blade clip onto the actual blade so you now have the part that clips the wiper blade onto the wiper arm on the car. Drill out the pivot hole to accept the 2.5mm bolt

now bolt the original clip onto the new "part required" and use a small lock washer under the nut and "Locktite" the nut to the bolt , tight enough to still allow the part pivot.

Cut the new wiper blade rubber to length -- I got 3 new blades from the one donor there is a metal part in the middle of the blade so you need a sharp hacksaw!

you then slide the blade into the holder and crimp ONE of the ends of the holder(part required) -- JOB FINISHED

See the photo "Finished Wipers" in my next post(only allowed 5 files with each post!!) for the car with the wipers fitted. They really are an improvement on the originals

Cheers!

Inspired by Robbie's work I went out and purchased 1 blade, similar to the Bosch but I got the longest I could, 65cm, and that gives me enough for 3 Morgan blades. As it turns out the little supports were held with rivets. The Bosch seems to use some sort of clip.

I carefully punched out the rivet with small jeweller's screwdriver, then carefully tapped the expanded end back to round with a small hammer so that it would go back in the hole. The support had been slightly crushed at that point so it had to be "adjusted".

I then removed the clip rivet from an old Morgan wiper using a Dremel tool and then opened the holes slightly to take the saved rivet from the donor blade. I fitted it all up and then peened the end of the rivet, and slightly squeezed the grips. The steel strips can be removed from this blade and re-inserted in the grooves. I used a very good wire cutter to start the cut and then when I flexed the very hard spring steel, whilst gripped in the wire cutter, they just snapped at the desired point.

After I fitted it to the car I adjusted the position by moving the blade in the grips so that it just cleared the bottom of the windscreen frame at the end of the wipe.

Here is the result before I fitted it to the car.
