I installed the TCI M2 frontend in my 55 2nd series.Although I have heard of guys doing it with the engine and front sheetmetal on I would not reccomend it. It aint that much of a job to pull the engine,and take off the front clip,or sheetmetal as some call it. At this point you have everything in full view to take the proper measurements,remove the old suspension,etc.On mine I had to install new side motor mounts,the original ones were on the front of the motor.Above all when you install the M2 crossmember,measure,measure then measure again to make sure everything is lined up properly before you weld it in.Good luck.
