I went to my local GM dealer to inquire about the cap screws>used to attach the Prop hub to the Corvair engine, and was told that the>part # is no longer valid. Would you happen to know what the new part number>is, or where I might obtain suitable replacement screws? Thanks.>>>That's an excellent question for the newsletter. Maybe you could find the>answer from:>Vitalis "Vi" Kapler (1033 Forest Hills Dr., SW, Rochester MN 55902)> 507-288-3322 I contacted Mr. Kapler as you suggested. He recommended either the CorvairUnderground(1-800-825-VAIR) or Clark's Corvair Parts(413-625-9776)for the capscrews.Since the Corvair Underground is about 25 miles from where I live I was ableto obtain the capscrews there.Things to think about:The owner of the Corvair underground asked me whether my 'vair was a manualor automatic transmission. After I gave him my most sincere "Huh?", Iconfessed what I was doing with the engine. I learned that Chevrolet used 2different(noninterchangeable) bolt types. The capscrews mentioned in theplans apparently are for the manual transmission engines.He DOES NOT have the bolts used in the automatic transmission. I bought aset, hoping I'd be lucky. I was. I didn't contact Clark's, so I don't know what their supply situation is.Anyway: (6) 1.0-11/32 capscrews Corvair Underground catalog #U-1165 $1.25 ea( Idon't think they come in a set).BTW Mr. Kapler said that if these were not available, the flange could bedrilled for a 3/8x24 thread for a standard AN bolt. I presume he wouldmodify the prop hubs he fabricates to accomodate this.On a related note, Precision Aerial Services in Florida reports in theirCorvair modification manual that Clark's Corvair does have flanges drilledto take the 3/8x24 bolts.
