and make sure to get the ac delco version if your gonna get a stock one. the other ones have been known to crap out not very long after install. delco is the way to go

I had a borg warner in my TA for a long time, never had any problems, got an AC delco last year when I did a tune up

well have fun changing your cap and rotor cause it is a day project. lot of parts coming off. i change mine you are better off to buy the whole kit cause that were the spark really comes from. MSD is a good pick goes really good with NOS.
