AMT/ ERTL Indy car /Cart info needed

[Sam I Am]

I have a couple different AMT/ ERTL kits with no instructions or decals.  I am having trouble finding anything on the net that shows all the cars that were produced, let alone the other things.  There must be very little interest in them for so little to be available.  Any help pointing me in the right direction would be appreciated.  Once I know what I am looking at,  then I will know what I need. I have one molded in white, and three in yellow if that helps. 

TIA

What scale is it? I built the. Newman Haas car that Nigel Mansell drove. It's 1/20.

These are 1/25 I believe.

They look a lot like these two, Sam:

Prior to the CART/IRL split, Indycar in the late 1980's had recaptured the magic of the 1960's-early 1970's. Both AMT and Monogram offered kits in 1/25  and 1/24 scale. The AMT kits were the better of the two. During this same period Tamiya offered a 1/20 car with the markings of Mario's last competitive ride. Revell also offered Indy cars from the late 1990's. While the Revell cars lacked engines and difficult engineering, they built up into the best replicas.

Thanks Casey, those look like the right ones. I can go put my needs in the wanted section now.

If you're looking for decals there are decals for these on a site called Indycals.  I don't know if it's OK to post links so I won't, but you can just search the name and find their site. I got stuff from them and they're good in my opinion.

I've built about three of those kits back-in-the-day and when finished they look really good to me, wish I still had them.
