I have the jegs cover im my garage i was holding it last night it will work for both water pumps i can take an actual picture if it make that much of a difference but getting the cover makes it possible to swap out a serp set up from a 90s pickup waterpump and all and keep your mech pump. the timing cover is based on a cover from a 1965 mustang with a 289. p/n C5OE-6059-A1 from what i could figure out.

 

this thread has kinda helped me only im going the other derection. I have a 95 f150 351w efi im putting in a 49 f3 I want to go to a v belt setup cause all I want to run is the (gm syle) alt and water pump think it will look cleaner then running delete kits and what not. ive got a 79 351w cover getting a standard rotation pump. so this thread kinda let me know what I got planned should work
