I used 00-90 look to be the right size. A there's on beating in just building all in fun. :I may need you to build me a body.
To get the parts to look the same. I make a patterns that i like then cut it out. I cut 4 pices of plastruct and tape together, then i use washable glue stick and glue the patterns to the plastruct. Then drill out 2 holes and put the nut and boltin to hold the parts not to mover, cut out and drill and sand.
