frame/ jag questions
its been a while since i posted, a new job and 2 kids got married,a allstate scooter project, while! and now it time to get back on track!
quick back ground, i have a 49 f-3 that i planned to convert to a f-1 and install a jag ifs and irs. i have f-1 box, sbc and tranny, 86 xj6 recently i've come a cross a 51 or 52 f-1 clean frame and only a frame, no axils. A
now here is my questions,
All f-1 are the same, right?
Is there any drawing / cutaways (or someone personal measurement) out there that will help me install both irs and ifs blind? with only the frame and the irs and ifs. As space is a problem (winter coming to minnesota)and i don't have room for a frame and a tore down f-3, I'm hoping to work on the frame only ( irs, ifs install, frame boxing, X member, and power train install) and leave the f-3 in storage (2hrs away) so measurment on locating the ifs and irs on the frame is what i'm looking for.
any and all info would be very helpful
thanks

I would buy the F-1 frame if it is good and $ are reasonable. I am not aware of any differences in F-1 frames. Locating the Jag IFS will not be an issue. I just buried my 49 but others such as Rusty should be able to get you the fore and aft measurement. I have provided the measurement in the past but cannot seem to locate it on the forum. Rusty also did the IRS. one suggestion that I would make is to shift the engine mounts/engine at least an inch to the passengers side. This will open up clearance with the R&P allowing more options for headers.
In summary, I would not be concerned with working off the bare frame locating the Jag IFS and IRS. There are enough of us on the forum that have btdt to help you thru the process. I say go for it!

axman,
Here's a link to a sketch from Old Fords Never Die.

I believe the frames are the same for 51.
Good Luck!

axman; Look up steel48; I used the measurements he put on his IFS install on mine. Read it and it will explain all you need to know about the IFS. I bought a cross member from TCI (total cost involved) for my IRS. I installed it right over the bump stops on my frame. The pumpkin bolts to the four holes in the cross member. You have to fab your own radius rods and stablizer bars for the rear housing. I'm not finished yet but it's not that hard to do just takes time. I also set my sbc 1'' to the pass side to allow room for the headers to pass the steering rod. Any more Q's just ask I'll do my best to answer or some one else will. RUSTY

axman, The lower flange of the frame rail at the front is 11" off the ground. I have not driven it and I would expect that it could settle another inch. As mentioned above take a look at 48 Steel gallery for photos and locating the Jag IFS.

axman; My double coil springs will mount on the outside of the frame. Still have lots of room for 15 in wide tires.
