Motor (MB 41 slat with a 45 engine) was professionally rebuilt and the head was bolted down (no studs were used) I provided the bracket for the oil filter but forgot about the air cleaner cross over to the carburetor. Question is it advisable or feasible to remove just two of the bolts, install the cross over support bracket and replace the two bolts. This easy fix approach seems to scream disaster over and over. What say ye!!!!!! Is it a reasonable risk or extremely hazardous.
