Understand,  but most manufacturers don’t provide the specs such as plug depth and actual OD. However, I was able to clean the original up enough to get the numbers , EPC16B and it crosses over to a Dorman 565-018.
Hope that simplifies if for someone else

Online it looks like the freeze plug kits for the 1987-up 4.0 include the smaller plugs.

NowI have the all the correct freeze plugs and ready for the installation . Has anyone tried putting the brass plugs in the freezer prior to installing for easier installation?

installed and placing the plugs  in a freezer for a couple hours before installation made it a lot easier.

Late reply, but for anyone coming across this issue of finding expansion plugs, i have wonderful news!

The Enginetech PK256B (or PK256 for steel) kit doesnt list the AMC 258 vehicles as compatible, even on EngineTech's website, but I ordered one for my '96 Cherokee 4.0L, and discovered it included all correctly sized plugs for my '87 Wrangler 4.2L's engine im rebuilding. Kit has 5 brass 2" plugs, 2 brass 1" plugs, 1 steel 2.14" plug for oil gallery, and 3 of the smaller threaded plugs. It's almost as if it was made for the AMC 258 :-)


I got my on RockAuto.com for $12, just had to look it up under 1996 Cherokee 4.0L since the vehicle compatibility isnt correct.
