Mike its ok
i didnt know the old style covers needed an o,ld style release bearing
my gearbox man built boxes for ford for 15 years
he had one in stock from 1989
just pissed off that i took it all apart myself put it all back together and it was fooked due to a release bearing

had to pay him now to do it all again with new beaing on the quick
oh well it best be worth it which i dont doubt
