Default Replacing AC compressor on 91 C4

I plan to replace my R12 compressor with a R134a compressor (Denso 471-0335). Also, I'm going to replace the accumulator/drier. Originally, I planned to covert the R12 to R134a, but the compressor was shot. I have the conversion kit with all of the o-rings and Ester oil on order as well. Is there anything else I should expect when making this change? And yes, a certified AC tech will do the work to capture all of the R12 refrigerant.
