Front end

I was thinking of this for my 98 Blazer... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7969293554&category=33645&sspagename=WDVW
It says it only fits the ZR2 models. Is the ZR2 front end any different than my LT?

I know that the frame is different but unsure if the width is the same.

Frame horn width is slightly different...
