Looking for a Dennys 3.5 driveshaft

Im looking for a Dennys 3.5" or 4" aluminum drive shaft or a 3.5" steel one. Would like chrome moly yokes. I havent taken any dimensions yet but its for my 87 T with a 200r4 trans and a stock rear. Thought it should sort of be a standard size length but....probably not. Let me know what you have....even if its not a Dennys unit
