Initially we note there is no clear and manifest intent by the General Assembly that 42 Pa.C.S.A. § 5533(b) be applied retroactively. In Commonwealth v. Baysore, 349 Pa. Super. 345, 503 A.2d 33 (1986) this Court recently addressed the question of the retroactive application of legislation which lengthened the statute of limitations for theft. The Act in question merely stated it shall take effect in 60 days. We noted that the legislature clearly can and does manifest its intent when amendments are to be applied retroactively.
