So today as per plan I went down to the local motor mechanic ustaads in F-10 Markaz and got the chassis straightened. In the end it was not as complicated as I thought it would be. A chain and a long pipe did the trick. Here are a few pictures. Due to the mass of people surrounding the car and supervising the one guy who actually did the job, I was unable to get an action picture of the deed being done:). It seems that the ustaad delivered what he promised.

Car up on the ramp. Chassis measured to be bent in the middle by 1"

Figuring what to do

Chain wrapped around the bent chassis member and a long pipe to yank it down and lots of onlookers to provide visual assistance

Final look seems straight enough. Of course the real rest will be if the tire goes in or not
