it was a LONG time ago, but when i put the 289, 4speed (top loader) in the Gold Bee Pangra Race car i used a Herbert and Meek kit, it came with all the mounts including the trans mount and was a total bolt in, the headers were weird but fit. I did have to use a sledge to dimple the firewall at the bellhousing but nothing else. I used a clutch cable but forgot where i got it from and it was reverse mounted and never worked correctly as the fulcrum and ratio made the pedal so stiff a bodybuilder whould have trouble with it. the bellhousing was from a '65 Mustang and Shelby flywheel and clutch. the floor was notched to fit the hurst vertigal gate shifter. I finally ended up putting a built C-4 with 2800 stall converter in it and had lots of fun. Pic's of the car is in my galley pictures. I also had to notch the front radiator support to get a Mustang II V-8 Radiator in it, also switched to electric fans due to clearance problems. That's as about as much as i remember on it now, this was in 74 so the memory fades, i'm sure others on here have more recent experience than I do. Good luck. Oh, sub frame connectors, slapper bars and a 6 point cage helped stiffen my Pangra.
