MWeldon has a hybrid F40 built with parts from two different ones to get the perfect (for his build) final drive ratio. They were in everything from Pontiacs to Saabs. Nice units but need some fab work and brackets to make right. A quick search on Pennoks will net you more info than you could need.
Other good options are the F23 (using in my build) and some of the hybrid/cryo getregs.
Also, sorry I couldn't make the meeting yesterday. Leaving town for a week for work so the honey do list is pretty intense this weekend.
