Chassis parts for older kits

[Duke Caboom]

I've been casually looking at kits for a number of years, particularly better known 7 type cars.

Every now and then I come across a car which has accident damage to wishbones etc but, apparently, not to the chassis.

Given the ease of access I always wonder why they haven't had the wishbones and track rods etc replaced, the tracking done and sold as repaired. I then wonder if it's because the wishbones aren't available and you'd have to have them made.

I have no plan to buy one. Just wondered.

Thanks
