I used the individual mounts but maybe this can help you figure it out.
IF your 49 is like my 52 it may work for you. On the front of my chassis there are three rivets on each side. Measuring back from the center of the CENTER rivet measure 15 1/8" this is the center of the motor mounts.

Using the mounts with the one vertical bolt the mounts are 19" apart and that 19" is to be centered in your frame.

I will scan a pic of my instructions and come back and post a link here later. I think seeing it will help you. Put you a piece of masking tape down the side of the frame to make on.

YOu can see the mounts I used if you look in my photobucket pics of my panel listed below. No matter what type mounts you use the center should be the same.

Hope this helps.

Edit: I used the big distributor and it cleared my firewall BARELY. If you use a small HEI with the external coil you should be fine. This is on my panel but others may be close or may work just fine?

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
