My name is Donald Niosi. I live in Punta Gorda, FL. I have a 69 Firebird with manual steering. I purchased a Saginaw steering box (PN 5691676) from a scrap yard in PA. They said it was from a 69 Firebird. It included the oil lines and pitman arm. I found an upper pulley set and crankshaft pulley set, plus steering pump and mounting brackets from a scrap yard in Iowa. I installed the pulleys and brackets, mounted the steering pump and relocated the alternator. Then I installed a Lares 201 steering coupler on the splined shaft of the steering box. Next I removed the manual steering box (PN 5879142). Then I removed the clutch return spring and bracket and dropped the exhaust from the left side of the engine. I couldn't get the power steering box to bolt up. The steering coupler was hitting the flange on the bottom of the steering column.The old box was 1/4 inch shorter from bolt hole to coupler than the new box. Can the flange be moved?The Flange is not splined like some earlier firebirds
Any information or knowledge you could provide would be appreciated.
