Made in the USA and built from stress proof steel, it is intended to replace a shaft that may have fatigue, cracking, or twist damage even when it still looks serviceable. This part is a direct fit for a wide range of classic Ford and Mercury V8 applications, including Ford F-150, Ford F-250, and Ford Mustang models listed below.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStandard replacement engine oil pump intermediate shaft\u003c\/li\u003e\n\u003cli\u003eStress proof steel construction for drive-shaft durability\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003eLength: 8.190 in. \/ 208.00 mm\u003c\/li\u003e\n\u003cli\u003eShaft diameter: 0.312 in. \/ 7.90 mm\u003c\/li\u003e\n\u003cli\u003ePart number IS-83 for easy identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eThe Melling IS-83 is designed for stock oil pump applications where the intermediate shaft transfers drive from the distributor to the oil pump. Because the shaft can suffer hidden fatigue or twisting over time, replacing it during an oil pump service helps restore dependable pump drive integrity. This part cross-references Four Seasons 53030 and Standard Ignition TS-83 for the same application. The IS-83 is a practical choice for classic Ford and Mercury engine builds that require the correct stock-style shaft dimensions and material specification.\u003c\/p\u003e\u003ch2\u003eVehicle Fitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFits 1977-1997 Ford F-350, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1978-1996 Ford Bronco, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1996 Ford E-150 Econoline, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1996 Ford E-150 Econoline Club Wagon, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1996 Ford E-250 Econoline, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1996 Ford E-350 Econoline, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977-1996 Ford E-350 Econoline Club Wagon, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1996 Ford Econoline Super Duty, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977-1996 Ford F-150, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977-1996 Ford F-250, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1991 Ford E-250 Econoline Club Wagon, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1987-1991 Ford LTD Crown Victoria, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1986 Ford LTD, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1983 Ford E-100 Econoline, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1983 Ford E-100 Econoline Club Wagon, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1981 Mercury Grand Marquis, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1978-1979 Mercury Grand Marquis, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1981 Mercury Marquis, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1978-1979 Mercury Marquis, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1971-1973 Mercury Marquis, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1980 Lincoln Continental, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977-1979 Ford F-100, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977-1979 Ford LTD II, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1979 Ford Ranchero, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977-1979 Ford Thunderbird, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1979 Mercury Cougar, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1977 Ford Custom 500, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1977 Ford Granada, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1977 Lincoln Versailles, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1977 Mercury Monarch, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1975-1976 Ford Elite, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1972-1976 Ford Gran Torino, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1976 Ford Torino, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1976 Mercury Montego, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1974 Ford Country Sedan, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1974 Ford Country Squire, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1974 Ford Galaxie 500, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1974 Ford Ranch Wagon, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1974 Mercury Colony Park, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1970-1974 Mercury Monterey, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1973 Ford Mustang, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1972 Ford Custom, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1971 Mercury Cyclone, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1970 Ford Fairlane, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969-1970 Ford Falcon, Stock\u003c\/li\u003e\n\u003cli\u003eFits 1969 Mercury Comet, Stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a worn oil pump drive shaft during engine service\u003c\/li\u003e\n\u003cli\u003eAddressing hidden shaft fatigue or cracking found during teardown\u003c\/li\u003e\n\u003cli\u003eRestoring proper oil pump drive transfer in stock engine builds\u003c\/li\u003e\n\u003cli\u003eCorrecting twist damage in older intermediate shafts\u003c\/li\u003e\n\u003cli\u003eSupporting maintenance on classic Ford and Mercury V8 applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify shaft length and diameter against the original part before installation.
