1965 GTO Hardtop 389 tri-power (WS), close ratio M21, 3.90 posi rear (ZK)
I am reassembling my '65 GTO's 389 (without internals), as I plan to paint the block heads, pan, timing cover, etc. then disassemble and discard the gaskets with painted edges to replace with new set when I do the final assembly of the engine. Anyway, there is a steel strap (1/2" wide) that "I believe" goes under the oil pan beneath the oil pan gasket piece that fits in the groove on the outside (curved) of the rear main bearing. The strap has tabs with holes for the rear-most oil pan bolts (which may also act as stiffers to keep the oil pan edges down at either end of the main cap. Anyway, I have a new oil pan and when I install the strap it doesn't hug the curved oil pan flange - it seems to float about 1/8" above it (larger radius). Is there some other gasket (or piece that I'm forgetting to mount) that goes between this strap and the pan? During disassembly (years ago) I did not take pics of this area, so maybe I'm installing something wrong. I'd appreciate any thoughts or suggestions.
