I was thinking of purchasing a 20:1 manual box from PST but I’m very hesitant now on going through all the time for the removal and install then finding out the new box has issues.
well i presume thay have many 1000s of happy customers
they seem to provide support
i'd suggest that your are more likley to get a perfectly good box off a site sponsor than you are off some other suppliers who just shift generic rebuilds.
my comments were universal to a sagniaw type box, the mopar box is very saginaw style, they were not comments about a specific maker or seller
