I'm a newbie to this, cut me some slack.

So it is common for the body to not fit quite right since the chassis is a tad longer? That is refreshing to hear, but I haven't seen anything about it posted on the forums. The chassis is designed to bend downward slightly at the back?
Any other ideas on how I can keep from losing a millions body pins and destroying the body? Will it make the RPM shock towers weaker where I heat and bend them?
