In the past, one of the major showstoppers in this conversion was the crankshaft register. Crankshaft registers need to be machined properly to accept the input shaft pilot bushing for the A-833, and a majority of the time, they were only machined to accept the hub of the torque converter for an automatic transmission application, or were only partially machined for the input shaft bushing. Your choices were either to have the crankshaft machined properly, ($$$$) or stick with your automatic. In the case of cast crankshafts, I've heard horror stories of drilling into oil passages when attempting the machine work! (If anyone can verify this, please let me know.) Fortunately, in 1994, Ma Mopar accidentally offered us an alternative- Beginning with the '94 model year, Chrysler began machining the crankshaft registers only in the "Automatic" configuration. Manual transmission applications received a new, needle-type bearing, which fit into a larger bushing that is driven into the torque converter register. The good news is that the torque converter register remained the same size as it has been since the mid-sixties! The bad news is that in most applications, the input shaft will need to be shortened approximately from 1/2-3/4 inches. This is an easy job with a cut-off wheel, but it could diminish the re-sale or trade value of your transmission should you decide to part with it. This part is available at most parts houses.
