4wd conversions

I am new to this site but it seems pretty informative so I am hoping you will all be able to help. I have a 79 K5 blazer, 6 inch lift, 36" Iroks, many more mods to come. anyway, me k5 is full time 4wd and I would like to convert it to parttime. I found a conversion kit through Jc Whitney made by MileMarker. Good company but I am wondering if anyone else has used this or has any other suggestions. Thanks for the help and I am sorry if this post has been done before, I did not see it on search of past topics. 3
