If you really want to do this ill tell you the BEST way.
1.Go here for search
www.car-part.com
2.Get a new(used,junkyard) trunk lid for a protege
est. cost at junkyard between $100 and $400 dollars depending on condition and with/without spoiler.Any protege sedan trunk from 99-on will work I beleive.
3.Locate a Lexus IS300 trunk lid on that site as well.Any color or year.Call to see if they have it.If so ,ask if they will cut the light pockets out of it and about 6'' all the way around.This will save on shipping it.Have them box it up and ship them to you.If they have a set of factory lights ,them great you can skip the next step.If they do have a set in good condition get them and the harness that goes to them,It will un-plug from the trunk lid and be about 12'' long or so.Have them ship it all together.Once again,saving on overall price of conversion.
Est. cost $150-$450(best bet to find one with damage to the lid but not to the area around the light pockets)
4.Call Toyota dealership and order New IS300 rear inner tail lights With the harnesses.They will come with the harness and bulbs.
Est. cost for pair w/harnesses...$300
5.Go to a GOOD custom body shop and talk to them about doing the conversion.They will have to cut the original Pro trunk lid out and fit in the light buckets.They will be welded and finished(filler bondo,sealer)and the trunk lid will need to be FULLY painted to match your car.I think your car is Black mica so matching should be easy.
Est. cost will vary on how many custom shops are in your area,but I would guess no less than $500 and no more than$900
So with all of this said,and going off of all the lowest estimates,you will have AT LEAST $1000 in doing the conversion.
I would only use a HIGH QUALITY and REPUTABLE SHOP for this conversion as doing this kind of work requires special attention to detail.
Just to give you a good idea of how much this costs,I will tell you what I paid to get my two conversions done.
90 Civic(4th gen) with TRUE Supra tails and CBR gas door,parts and labor installing and finishing(NO PAINT) ...$3700
95 Del Sol W/GS300/400 inner tails,fully done finished and painted....$1200
I have been doing custom cars for a long time and also know my way around the body shop.I have done much fibrglassing and a little body work.My buddy also did the Del Sol conversion while we were in the middle of a TOTAL re-paint and that is still how much I had invested in it.
Worth it?....To a normal guy....NO!
To me,who is a die hard show fanatic and X-treme show goer and winner.....PRICELESS...MONEY WELL SPENT to show everyone up when I go to shows and take home a nice BIG trophy,not to mention much respect for having one BAD ASS CAR!
This is a major decision that only you can make.You must decide what you want the car to be BEFORE you start anything.IF NOT,everything will come out looking like an afterthought NO MATTER how good the bodywork is.
PLAN ,RESEARCH AND STUDY....THEN EXECUTE!
This is how show winning cars are put together!

TRUST ME, I KNOW!
