After talking to Henry and crunching the numbers I've decided to bring the IM back home.
With the money I have in this car it just makes sense for me not to sell it. I'm hoping I'll fall in love with it again, just like I did the first time I owned it, way back in 2000.
Here's a link to some photos. Henry included a couple of photos of the Vintage Speed shifter to show me the modified shaft. Because of some weird anomaly with my pan car and the angle of my seat it is a bit of a reach to shift into 1st and 3rd gear. Both Henry and I also had the same problem with my CSP shifter.
