Front motor mount - how does it attach? 2 bolts or 4?

[29UJohn]

How should the front motor mount be secured between the engine and the frame?  My 29U's is attached with just two long bolts.  However, I saw one 29 with four small bolts, two to attach the mount to the engine, and two bolts with nuts to secure the mount to the frame.  This seems like a better way to mount it.

I have 4 bolts on mine that's the way it was when I got the car.

My '29 Ply Coupe front motor mount was a little on the soft side so sent off and was re-vulcanized. (Thanks to Antique Auto Parts Cellar and Tom Hannaford) It was attached with two bolts and nuts to the frame and two bolts to the engine.  Log in to see attached photos. Happy Motoring!!!! - Rich

Thanks!  I will re-attach the motor mount the correct way.  Tom Hannaford revulcanized mine also and did a great job.  It is one of his specialties.
