Bellhousing question

To the best of my knowledge,the bellhousings are not body specific.The early a body z-bar won't work with the later bellhousing.The early a bodies had small clutches, 9 1/2 and 10 inch.the later cars had 10 1/2 and 11 inch clutches.Brewers performance makes a z-bar and the bracket that supports it on the bellhousing,it's a no hassle bolt in and go kind of thing, unless you want to modify your z-bar yourself.I did the same in my 66 signet {71 aluminum bellhousing}
