63 Rear Spindle Supports

[Michael G.]

Early 63's had unique rear spindles, (no web between the legs) but were those parts replaced with the webbed parts for the start of 64 or late in 63 production?

Thanks,

Thanks,

I believe you are referring to spindle supports not spindles?

Re: 63 Rear Spines

Michael, I never knew how late in production the early spindle supports were used on the '63. It seems that is not common knowledge.
Maybe Jorjorian will chrip in. JD

Re: 63 Rear Spines

Dick, yeah, I meant supports....thanks.

Jeeez, and the auto-correct changed the title from "spindles" to "spines". It's a wonder you guys can figure out my gibberish....

FWIW, here's off an early calendar '64. The other side is cast A_6_4.

Mike, I have a chapter member here in N.E. that has a July car 120xxx He has one spindle support with web and he has the 63 date. He may catch this post and answer you.

By the way, the casting number on the supports and the finished part number for the supports never changed. So, the addition of the "webbing" must have been accomplished by a revision to the specs for the part. The left side and right side castings were the same. The only difference for left and right sides was the machining for the finished parts.

Re: 63 Rear Spindle Supports

Both spindle supports in my April 63 car have the web. They are dated B 7 3. Yes they are 63's not 73's

I don't think a cutoff date will ever be determined.

Re: 63 Rear Spindle Supports

Harry, I think maybe you answered my question. My April car (13696) has webs and I was thinking maybe the supports had been replaced. Sounds like they could be original. I'll look for dates on them.

Mikey, with that one web, your car is about half prepared for amphibious work....

Thanks,

Re: 63 Rear Spindle Supports

Neither spindle arm on my March 18th built 63 ( 10862 ) has the web.

Re: 63 Rear Spindle Supports

One of the supports on my May 14th 63 had no web on it. I had to replace it as it was cracked when I bought the car unfortunately I didn't bother to look for a date on it.

Re: 63 Rear Spindle Supports

It's beginning to sound like the first webbed ones arrived in late March or April. After that, they probably had multiple boxes of supports in the plant at once, some with webs, some without. Lacking a distinguishing part number, they'd have put them on the line in whatever order the box presented itself to the hilo driver, without regard for physical differences.

Thanks,

Re: 63 Rear Spindle Supports

Mike, I think its as Harry S. says its appears that there is not a clear cut date on the switch. I was looking at pics of a 63 chassis resto on Wilcox Corvettes website if I remember they a one with a closed web and one without on a original chassis.

One thing to keep in mind here: I realize that the "non-webbed" supports are the correct ones for most 1963's. However, you don't suppose that GM added the "webbing" because there was no problem at all with the supports without it, do you?
