I am parting a 75 Ghia. Let me know what you are looking for and I will see what I have as soon as it warms up a little. Darn cold in Tn. PM me if you like.
I bought a 1980 Mercury Bobcat several years ago to make a drag car and it had the c-4 in it behind the 2.3. I used the tranny and sold the bellhousing. They must have been in several different models and years.
