I have searched high and low in this form and the internet to try to find the scale size that rotf optimus prime fits into. What I mean is that is he 1/32 scale or 1/25 scale. see with model semi trucks the scales are all over the place. I would love to know where leader class rotf optimus fits in with those scale so I could look up parts to modify for the toy. I was comparing it to long haul trucker model trucks . If you type in new ray usa dot com into your address bar you will find out what I am talking about. It won't let me post the site here. If you click on the 1/43 scale I think he fits in with that, tho I am not 100% sure. I am sorry if this is a repeat post. I was trying to find the trailer impact guard for the UFO annular trailer I have so I could make it more movie accurate. I have come close to finding what I need, but I may have to scratch build. thank for the help.
