The passage door handle broke on my FD, they are made of plastic and had become brittle with age. The mechanism had also become stiff which through lack of use which did not help. I super glued it back together as a temporary measure until I had found a replacement.
I found a pair of powder coated aluminium handles on eBay from napolproducts for $99.95 including postage to the UK. I had to pay an additional £11.81 for import VAT and Parcel Force added another £13.50 clearance fee.
It took about 30 minutes to remove the old handles, clean and lubricate the mechanism and fit the new handles to both sides using a 10mm spanner and a couple of cross head screw drivers.
The replacement handles match the surrounds well and should last the lifetime of the car.
