The T-topparts are STAINLESS STEEL replacements for GM part # 20066040 (RH) & GM part # 20066041 (LH). The restoration part for our customers that will NEVER rust and can still be ordered without worry of being discontinued...as GM has done. The GM pieces were stamped steel and were prone to rust as water and moisture tended to "sit" in the corners. With the weight of the t-top on the plate pressure is applied to the reatiners welded in the roof. Once moisture is trapped & paint wears the rust begins.
This item is made of stainless teel - NEVER RUST AGAIN!
Fits ALL GM Gbody Cars! Replaces GM part # 20066040 & 20066041
