Vigilante Yank where to buy

Most people seem to get the yank or vig converters. What is the best place to buy either of these? Are any other companies building good converters for the 4L60? They are sooooooo expensive!

Well, I'm a huge Vigilante fan having had one in the car since 1996....You definitely get what you pay for, here...After 8 years I just sent the converter back for freshening only because I was rebuilding the trans and wanted everything fresh...Great converter, great warranty (you'll never need it), 5 solid tenths in the quarter, and docile enough to drive everyday. Go to www.converter.com I've always dealt with Vicki...Its worth every bit of the $700....:bow:
