First, thanks to Bruticus and Grimlock531 for their help with figuring out how to remove the door panels.
This was made by swapping bits between a Sideswipe I have lying around for a custom and Red Alert.
Red Alert now has Sideswipe's white arms, thighs (but I kept Red Alert's red highlights and knee joints), head piece and central column piece (the thing the head goes up and down in), plus Swipe's pelvis.
I can't figure out how to remove the grey panel underneath the car hood but I quite like it...
I also gave Red Alert Sideswipe's gun and engine block (didn't like Red's unpainted gun and engine)
