Hi,new member first post of 30 before I can use forum fully I recently purchased a Haynes manual for this car which offers no info on dash removal etc.I also purchased a Mercedes style twin disc set which wont work for me.[TIS system] The cars engine was kaput and a non mercedes engine is in place. I wish to access dash to tidy up wiring and adapt the instruments to the new engine and trans. 1974 450 slc. Questions- 1.Is there a useful manual available [not haynes]? 2.If a kind somebody could email any useful info re wiring or dash disassemble that would be great [petespipes at hotmail dot com] 3.Should I be looking at another forum for this type of info? Thankyou in advance for any advice,I am located in Brisbane Australia. Cheers.Peter.
