Hi,
I recently purchased a 1975 450sl....fairly high mileage (200k)
but it an Arizona car, runs strong, and has impeccable records. There are 2 items I have questions about.

1. it seems to have a leaky fuel injector. I have ordered a new injector and o-ring kit. Is this something I can just plug in? or will adjustments have to be made (I have ordered a 107 manual on cd, it just hasn't arrived yet) also, are there any special tools needed for the swap?

2. I have read all the horror stories about the catalytic converters being located under the hood in the 75' model.
realizing I cannot remove them, are there options as far as relocation? my first thought would be to purchase 2 new converters and have them relocated to the underside of the chassis with a new pipe to the exhaust manifolds. the other idea is similar (depending on if they are connected to the exhaust manifolds or not) can I swap out 74' exhaust manifolds for the 75's and then relocate the converters to the undercarriage?

thanks..
