Europe residents- looking for certain toy

[gotbunny]

Ok my grand mothers 90th birthday is coming up and I'm looking for a toy that she has been wanting to get for the great grandkids. I have look high and low for it in the US and no luck.
It is a building set made in France by Jura castor. 2 big red square blocks that you can hook with blue bolts and nuts long  or different shaped yellow flat pieces. Came with wheels an other parts also. I have no clue what the set is called, she got them for us kids when she was in Europe between 85 and 1991.
Any info or what the set was called would be great. Or if you have one for sale. Mostly just need the big red squares. We wore ours out.
