bankruptcy look back period

Looking for advice on if (and if so, with whom) to refinance my car?
I currently owe about $9,250 and have 19 payments left at $500/month on my car. The trade-in value is a bit over $13,000 (private party is closer to $17k). I have decided to keep the car for about 2 more years. The original loan was at 2.9% APR, so there’s barely any interest at all left to be paid.
I’m looking to refinance ASAP to a 4- or 5- year loan, with a 45-60 day no-payment period up front.
I filed for bankruptcy in 8/05 (just under 18 months). My credit before and after was perfect (no derogatories at all), and my credit score is back to between 661 and 704 depending on the bureau.
I also just began a new job, and relocated to a new city.
So here are my questions: What kind of interest rate should I expect to get approved for, should I expect to even GET approved, and which company is likely to provide me with the best result?
No matter who you finance with, because of bankruptcy you will not get less than the 2.9 you have now. And I doubt if any will let you go60 days no payment, 30 max.
