I'm in the process of reassembling my front end (pulled motor and transmission, diassembled, painted everything, etc...) and I can't find the seal on the driver's side inner fender well to the firewall. On LMC's link, it lists the passenger side (Item 10)Truck Parts and Truck Accessories but not the other one and I haven't been able to find it listed any were else. Has anyone else been able to find it or have an alternative? Thanks.

 

The '73 model year only used two different seals for right and left (RH D3TZ-16B126-A & LH D3TZ-16B127-A). 74-76 used the same seal on both sides, this was also the LH seal for the '73 (D3TZ-16B127-A) 77-up didn't use the seal.

 

LMC's seals are made of plain rubber sheeting. I ordered a set n 2010 and it dried out, cracked, and fell apart after a couple of years.

A better option is to use the old ones as a template and cut new ones out of EPDM rubber sheeting (pond liner) which is UV resistant.

NPD offers them but don't know what material is used.

 

Thanks gentlemen, thats exactly what I needed to know.

 

dont buy LMC seals . I did, they are plain rubber like HIO Silver says. I could never get them installed. I bought a set from DC , perfect fit, easy install.

 

I ordered and received one from DC and JBG (which came from DC). To use one on the driver's side it has to be trimmed and additional hoses punched. I now agree with HIO on just making your own. I'm pretty sure you can even get comparable replacement pin inserts (attaching doo hickeys) at AutoZone...
