A855 - 5 Speed
There is much more to the 855 story but it is not my place to explain it in here.
It's not the best situation for a product that really improvises the old car's driveability and bolts in directly without fuss. The other product is garbage and requires cutting.
I am unable to determine based on the posts who owes who, if the op is owed money it is not abundantly clear as to why.
If anyone out there has significant funds you can buy out the the project and fix it's woes. If you don't want an 855 try 3.23's or 2.94's with a 2.66 1st gear ratio 4 sp
