My blocks date stamp was 08/90. So maybe for an early 91 model.
5.9 (360) Magnums came out in the 1993 models I believe.
The LA roller and Magnums use pretty much the same roller lifters.
The setup is exactly like this:
With these "dog bone brackets".

Yeah, Chrysler sure knew what they were doing when they designed and built these. I've had little to no problems with these stock roller lifters and they're actually pretty quiet.
*I lucked out with mine*, so I didn't need the hydraulic roller retrofit kit. And from what you folks are describing, not a good investment.
*7 years ago, I got the motor from a 56K mile 1991 Ramcharger that sadly was at a recycling center. After 20 minutes talking to the manager. I was able to get the whole Ramcharger for $500 with a salvaged title. The motor was clean, and smooth running so I kept it.
The PO who was a college student burned out the transmission because after his grandfather gave it to him he never checked the transmission fluid and didn't want or know how to get it fixed. So he salvaged it.
The rest of the truck I gave to a young girl who's Ramcharger was in rough shape but was willing to fix hers up.
After hearing her (she was 19) talk about the ramcharger and her knowledge of them, made me happy there is hope with some of these millenials.
