Hey guys, I think I messed up. I purchased a 955 Techart lowering module only to realize it is not compatible with 04 models which were built in 03. Unfortunately, mine was built in 9/03. I have done some research, and it has pointed to possibly changing the level sensors to the post 04 versions, but every post I read is very vague. Does anyone have part numbers or expertise on the subject? Thanks!
