I am a Pontiac dealer and we sell the conversion for 525.00, you will need to have it painted and the exhaust will have to be custom made by an independent shop. If you have any ?'s email me at [email protected] :cheers
Ya i have actually seen an 04 at my dealer, with that done. I thought it was an 05' and felt like an idiot when i asked about it only to find out it was on 04.
IMO tho, i dont like the new rear end look on the 05', but thats just me!
