- How difficult is the electrics? yours was already an injection model.. mines carb so im assuming a lot of wiring?
Regardless of the original car, you've got to remove all the engine electrics from the W123 loom then remove only the engine management and other engine electrics from the W126 loom. To be honest, a carb'd car would be easier if anything.
- Mounts?
They're bespoke, I had a blacksmith make mine based on Martyn's measurements, they were about £50.
- Gearbox? did the 560 box just fit in place?
Yeah, it fits right in - no chopping. Even the 230E saloon gearbox crossmember fits
As I say, I can't take credit for much of this car's build - Martyn had all the knowledge, I just pointed the spanner where I was told to and made lots of tea.
You should definitely do it, though. It's a rad conversion. And, as you know, free pipes on 560 engine sounds sooooooo nice. Even nicer when it's coming out of a W123
And six points? You're not trying hard enough!
