Joining the off topic thing...Scooper that is one nice machine! My buddy did exactly what you did! 89 motor in the thing and it hauled the mail like no other! He also raced one and told me at the time the 911 was easily trounced on because they were so unbalanced compared to the 914.
That vehicle is a beauty and I am completely jealous! Brings back some seriously fond memories.
I miss mine, but not enough to go back into that money pit again!

Now, back on topic.
