if anyone is interest in talking a bit with me and helping me truly find out whether my gorgeous girl is a true iroc-z or just a z28 i would very much appreciate it please guys help me out im beggin someone......1G1FP87F4FL those are the first eleven digits to my vin unfortunately my RPO code in the center console has been removed i've had the car for 2 years and have never really been sure please help me!

 

1G1FP87F4FL =

1G - US built Chevrolet
1FP87 - Chevrolet Camaro 2 door coupe
F - engine type - 5.0 (305 cid) TPI LB9
4 - check digit
F - model year 1985
L - build plant Van Nuys, CA.

The LB9 was available w/ Z28 and IROC in 1985 but only w/ auto tranny. IROC RPO was B4Z. Is that some where on your car?

 

no the RPO code in the center console has been ripped off thats one of my problems the tacometer is correct the speedometer is correct the grill is not the decals on the sides are right but some things seem sketchy i wanna know for sure...

 

Maybe this will help then.

already been there haha just need someone who can really just somehow help me figure it out thats knows a sure way to tell i know the suspension is differant but dont know how to tell could use an "expert" lol

 

i have a 1985 z/28 with tpi . the only thing you can do is look at the sticker in the console see if said b4z and also in front of the passgner side on the dash it should say irocz28.mine just z28 tune port injection also iroc add the wonder bar on them help this help

 

like i said the RPO codes inside the center console have been torn off sometime in the past i do have the Irocz28 decal on the passenge side but only a z28 decal on the back of the car like i said some thing make sense some dont i dunno how to look for the wonder bar???? im new to this

 

but the iroc-Z decals on the side of the car are right and another question i had is the pain mine is a Dark Blue with silver damper and skirts so its two tone i was under the impression that there were no two tone Iroc-z's and also like i said it doesnt matter to me either way if she is or if she isnt i just want to know for sure D****t...

 

The Steering Brace (also known as the Wonderbar) performs two functions. First, it ties the left and right sides of the frame together under the front of the car, which maintains the correct geometry of the pitman arm and idler arm during cornering. You can think of it as a Strut Tower Brace (STB) for the bottom of the car if you like to see a pic of one go hawks third gen and look under Strut Tower & Steering Braces because mine did not have on it and all the iroc i have seen have this bar on them

An easy check is the door placard, which should provide info for 16" wheels. No 16's in 85, no IROC. No two tone IROC's.

Stand infront of your car with the hood open look down under your fans do you see one or two bars going across if one then no iroc if two then you have a iroc

 

ill definately check that out tomorrow morning and let you know what i find, so if i look down and see two bars its an iroc so is that a sure way to tell.....could you not just add a wonder bar onto a Z or can it not be done that way

 

yes you can . i put one on my z/28
