249 to 242J?

I found a complete 242J from a 98 GC 6cyl at the salvage yard today. My question is can I use it to replace my 249 in my 98 GC v-8(5.2)? It is getting cold here and I have little $ and less daylight lately to do the swap. I am going back tomorrow to get the tc, rear driveshaft and shifter etc. From what I can tell by reading this site, it is basically bolt in, other than the info center and linkage. Am I far off thinking this? Thanks for any help. I just want to be sure I am not getting over my head considering the time of year and my lack of a warm garage.

I don't think you need the rear driveshaft. Since you're matching the model year the yoke should be the same. Measure yours before you go to avoid spending un-necessary dollars.

good luck

yes it is bolt in. likely the 242 has an external slip yoke which means it is 1.5" longer than the 249. so you will want to get the rear driveshaft from the donor.
