Looks good! I notice the cord going to the motor is pretty tight in the cutout for the motor bracket. I overlooked that, and will modify the file for the 34-4xx Delta machines. If you feel it affects the fit adversly, drop me a PM and I'll send you another bottom piece.
Actually I may have the cord in the wrong place. I've had the motor off and back on several times as I've moved, stored, moved and set up again.
I think it originally ran through the motor support and had a small wire tie to hold it in place. You may want to check with some other Delta owners before you change anything.
