When installing float a motor

When installing the float a motor mounts do you use the little bushings that go through the frame like the original mount or leave them out? My frame did not come with mounts and the float a motor kit does not have these bushings.

Leave them out, the mount bracket bolts directly to the frame rail.
If you decide to put Float-A-Motor mounts in the front, P.M. me and I will explain how to do it correctly, as the factory instructions are VERY INCORRECT! If done their way, it will vibrate worse than the stock mount!!
With the addition of the front mounts, properly done, it makes a world of difference in smoothness, Even with a stock crankshaft!!

I posted it before, but no response---Here goes again:
Instructions are O.K. except for drilling 3/8 inch holes in each side of the front crossmember. That way lets engine vibrations transmit DIRECTLY through the long bolt from engine crossbar to the front crossmember. Just enlarge the crossmember holes to 1 inch, using a Harbor Freight Uni-Bit. This allows rubber biscuit to squeeze into the holes in order to insulate the long bolt from making metal to metal contact with the crossmember.
I had to add 2 thick flat washers under the engine mount plate to align the crank bearing with the crankshaft ratchet nut.
 
just to add a little more info to what bill said, dont tighten the side float a motor mounts to tight, if you do you will get a lot of viberation just like stock mounts, tighten them down till the rubber pads are squist a little, you may have to tighten a few times till you get them tight but not so tight as to generate viberations

GOOD POINT!! I hope the manufacturer of Float-A-Motors reads this and revises their installation instructions. This kit is a VERY GOOD product if installed correctly.
Also, don't over-tighten rear mounts also.

Thanks for the info Bill, maybe thats why some people say they{mounts} don't help.

I feel that even a bone stock Model A engine gets a bad rap for being for being a vibration generator.
With front & rear Float-A-Motor mounts, add a very flexible rear exhaust hanger, unhook side pans from engine, and it's like driving a whole DIFFERENT CAR!!!
I formed curved flat iron braces bolted to frame rail under side pans to stabiliize them from shaking.

Could you post a picture of these.

Thanks Joop

No pics, I sold my "30 coupe with that modification. Will be soon doing same on "VERMIN," my '29 coupe. ( the one in my avatar )
