Hmmm,,, I'll check it out tomorrow and let you know.

sandblaster:
In the mean time I am trying to figure out how I want to mount the engine mounts.
I know a lot of guys weld the mounts directly to the frame but it will make engine removal in this 250F frame all that much harder.
So, I am thinking about drilling through the square tubes and welding in aluminum tubing and running bolts all the way through the frame tubes.
Here is an example:



What do you think about that?
Or, do you have a better idea?
