I am going to be install a Vig 3200 stall next week. I had thought I had read somewhere before that you had to buy shorter bolts because the stock ones are too long? Is this correct? If so what size and length do I need to pick up?

 

For the Vig3200, yes that is correct! You may want to contact Precision Industries for that, I don't recall off hand what they used.

 

not sure if this is the same case scernio but i just just a 3000 tci in my 4l60e and it came with bolts already...so you might just get lucky.

 

I got mine used and called PI to ask the same question - they sent me some for free.

 

Me too, they are 10mm long. If you have to shim the converter, you will also need longer bolts. Check to see how much you have to shim the converter during the install and if you have to shim it, add that much to the 10mm length. You can grind down the length of the stockers if you shim it to make the bolts the right length.

 

I just install my 3200 vigilante last week and the bolts they told me to get were 10 by 12 by 1.50 mm your local hardware store should have them i got grade 8.8 bolts with some lock washers. Oh by the way you will love this converter!
