not sure but the length but i know you cannot use it...it wasn't the fact the lenght it was how far it came away from the block...the bracket that bolts on to the motor was either too far or too short from the motor(i forget which one)...the automatic tranny bracket is different from the manual bracket that bolts up to the tranny...we tried this and we couldn't mount it up since the spacing was different for the manual and auto...
