I’m trying to see if it’s possible to add EPAS to my 64 Greenbrier. I have never removed the steering box or column out of an FC. it looks like the steering box and column are attached as one unit vs the cars. Does anyone know if this so, and if the column can separated from the steering box. My Greenbrier is rather pristine so I don’t want to hack into it without knowing more about it. In another thread some have suggested using an “ididit” column. I need to know more about this. My assembly and parts books don’t offer much detail & my service manual doesn’t elaborate either. Thank you to anyone with experience to share.

worm gear to steering wheel splines is 1 piece

Mike, a '64 FC should have a column tube that separates from the box. You should see a clamp right at the floor board. But yes, the worm shaft is one piece. You certainly have good access for an EPS conversion on a FC. I recently worked on an FC that had a Ididit manual tilt column spliced to the FC column. It was nice except I didn't feel confident finding out they had a single set screw coupling holding the shafts together - and it was loose! I will follow your progress as I may convert my Greenbrier to EPS someday.

Since steering shaft is full length and tube is designed as a permanent component to steering box, front bumper and left lower body extension must be removed to service a FC steering column. See pages 4-19 and 10-92 through 10-93 in your '61 Corvair Shop Manual for an explanation to properly R & R FC steering column. Easy job if corrosion isn't an issue.

Thanks to all for your input. I spoke with Geoff Mason at EPAS Performance in Sarasota, Florida via email. He told me to watch their Corvette C1 installation video. It would appear the steering on early Corvette is almost identical to the FC.

As vairchet pointed out, removing the steering gearbox requires removing the bumper and left lower extension panel. Then of course I have to remove the steering wheel, turn signal and housing and steering column to dash clamp in order to slide the steering shaft and gearbox. And then the need to cut the steering column tube and worm gear shaft. However, I have pretty good shop tools (Bridgeport mill, metal lathe, etc) to make it possible.

Hello Dean,

Missed seeing you at the Vairs at the Fair last week

I’ll start back up on the EPAS in a couple of weeks. Right now I have to help out with our local Corvette Club annual show. I’m trying to find an FC column and gearbox to try this before chopping on mine. I’ll take pictures with details if and when I get it done. EPAS Performance has kits for Corvairs but only for PG applications. Mine are 4 speed. They’ve never tried an FC and are eager to develop it. I don’t want to do a hack job, it must be 100% clean and neat.

They probably did the PG Corvair because the clutch and brake swing pedals are in the way with a four speed. Of coarse that wont be factor on the FC with pedals in the floor
