Every part # shown is a valid GM # (except the front bumper upper mount). Everything else bolts on to the newer front end (lower splash shields, front air dam etc.). I hope this will help someone out.

 

thanks for this posting, it helped me out alot what did all these parts cost you, and where did you get them from?

 

Most of them from ebay! Also got an SS hood on ebay from a guy who luckily lives 2 miles from me for $550.00. Total I think I spent around $1100.00. Most of the parts are cheaper to buy from GM than the junkyards (not all, but alot). Good luck!

 

I was thinking of doing this swap. How hard was this to do? After getting all the parts did it just bolt on, or did you have to modify anything? Also are from the doors back the same for all the years the same except for the spoiler and tail lights. I have a 93 Z28 and I want to make it look like a new SS. There is a camaro on Page 4 of the new RKSPORT 2003 enhancement catalog that is sweet. Thanks for the part #'s.

 

droptop on the parts number where you said gm change the number for the front bumper upper mount, would you happen to have a picture of this part, i want to make sure im getting the right part, becasue the number is dead

 

Sent you e-mail chasmanz28, sorry for the length! As far as the rest of the car, it is the same. I had no problems just bolting the front end on. I had seen on this board that someone once said that the LS1 front end was a little shorter than the LT1, but not in my experience. Everything was pretty simple.
