Hey all, I was about to order a diff cover/girdle from TA for my 72 Skylark. I had picked out the BOP 8.2/8.5 10 bolt rear diff cover (TA-1808) but the Lady I spoke to on the phone had advised I needed the corp diff cover instead (TA-1807). I assume she knows exactly what she's talking about since they provide them, but just wanted to confirm on here before ordering it since I'm up in Canada. <TABLE class=products cellSpacing=0 cellPadding=4 width="100%" border=0><TBODY><TR><TD width="59%">Product ID: TA_1807 Chevy 8.2"/8.5" 10 Bolt Rear End Girdle - Original </TD><TD vAlign=top align=right width="15%">Details </TD></TR><SCRIPT language=javascript type=text/javascript><!--function formvalidator2(theForm){if(theForm.optn0.selectedIndex==0)return(chooseOption(theForm.optn0));return (true);}function updateprice2(){var totAdd=159.95;if(!isW3) return;totAdd=totAdd+pricechecker(document.forms.tForm2.optn0.options[document.forms.tForm2.optn0.selectedIndex].value);document.getElementById('pricediv2').innerHTML=formatprice(Math.round((totAdd)*100.0)/100.0, '', '');}//--></SCRIPT><FORM name=tForm2 onsubmit="return formvalidator2(this)" action=cart.asp method=post><TR><TD colSpan=2>Original Chevy 8.2"/8.5" 10 Bolt Rear End Girdle fits all Chevrolet and GM corporate produced cars and light trucks with 8.2" & 8.5" ring gear and 10 Bolt rear ends, including the Grand National and 1/2 ton trucks. </TD></TR></FORM></TBODY></TABLE> <TABLE class=products cellSpacing=0 cellPadding=4 width="100%" border=0><TBODY><TR><TD width="59%">Product ID: TA_1808 B.O.P. 8.2"/8.5" 10 Bolt Rear End Girdle - Original </TD><TD vAlign=top align=right width="15%">Details </TD></TR><SCRIPT language=javascript type=text/javascript><!--function formvalidator4(theForm){if(theForm.optn0.selectedIndex==0)return(chooseOption(theForm.optn0));return (true);}function updateprice4(){var totAdd=159.95;if(!isW3) return;totAdd=totAdd+pricechecker(document.forms.tForm4.optn0.options[document.forms.tForm4.optn0.selectedIndex].value);document.getElementById('pricediv4').innerHTML=formatprice(Math.round((totAdd)*100.0)/100.0, '', '');}//--></SCRIPT><FORM name=tForm4 onsubmit="return formvalidator4(this)" action=cart.asp method=post><TR><TD colSpan=2>Original B.O.P. 8.2"/8.5" 10 Bolt Rear End Girdle fits all '64-'71 Buick, Oldsmobile and Pontiac 8.2" & 8.5" Ring Gear, 10 Bolt rear ends and some B-Body cars, '67-'71 Firebird. </TD></TR></FORM></TBODY></TABLE>
