Thats a pretty neat swap. Those little merkurs are interesting cars and have more potential suspension wise etc. than most people give them. Looks like you got a good start on the swap as well. Good luck getting it finished up.

8.8 needs mods to fit . not much but you will need custom axles Ford cobra inners and Xr's outers. It is not cheap. A bunch a U.K. guys are buying them from the states from the guy who is modding the beams for people. it is a great alternative to the 7.5 with big dollar ring gears and limited ratio's. It not that far off from a 9" "Fords 909 race spec" especially in a light car like these. plus I like the ratio selection and price of the 8.8 ring and pinions.

Trans tunnel was just some banging on the underside of the tunnel. right under the blowerbox about 3" back. trans mount was a T-5 coversion piece that can be had for about $75 from a company called Rapido.

this swap would be a hell of alot easier if I switched to a compression strut design. trying to shove the T-56 trans up over the swaybay is where all the banging begins.

turbo's are in the future.

got some more work done this week. DBW pedal mount done, clutch master mount finished.

New carshop inc. oilpan came in and motor mounts. Nice piece similiar to the Autokraft pan.

Got the Corvette exhaust manifolds and cat's. I am happy they clear the steering shaft. so no moving of the steering rack.

Almost done. maybe by the end of this week it will be running.
