2002 bravo 1's with -2" imco's. do I need certain drive spacers and couplers for this combo or will regular bravo 1 spacers and couplers work? thanks

The Imco spacers & shaft couplers are what you would need. You will need to know how thick of a spacer you need though. They come in 1/2" increments if my memory is correct. If you need them feel free to give me a shout. I handle their products.. Jamie / Lakeside Restorations 570-639-2628

Only a couple of companies make the spacers. I would just use Imco's. They come with a new longer coupler and new studs/bolt. All you need is 2 standard upper to lower gasket sets per drive.
