Hi UncleBa, welcome to the robot community. Is it the newer argos motors you have? Just to make sure. They can be seen in my video on YouTube, , note the price has since increased since that video.

I usually accept payment via a friends and family payment through PayPal, as it means I can sell cheaper to you as I don’t get the fees. You are also guaranteed the parts though as it’s my name on the line if I don’t deliver! That’s why I’d rather have a friends family payment.

Are you based in Uk? If so, 2 mounts would be £2.50 postage, 3 to 4 is £3.50p. Send me a PM and can discuss if the measurements suit your design and if you need a change to the standard design.
