Yep, I ran the Cross-Boss and the 875cfm Inline. Check out my avatar...a 1425cfm 'B' Inline on my current Boss 429 (Can-Am 494) engine.

I'm pretty sure that the original Shelby part is different than the repro. Same dimensions but different look. In the distant past I seem to remember a rebuild kit (service?) being offered for the original - pre repro availability. The arm on the steering box was also longer and the box used the same quicker ratio as the power steering box.

Use something with a GL4 rating. GL5 could eat the syncros depending on what yours are made of. I'm pretty sure 90W was the original rating. I agree no synthetic. I did some homework on this when I got my Model A. The PO had used synthetic and the syncros in my 39 trans and overdrive were too slippery to engage without some grinding. Changed to orig recommended fluids and all is good.

Thanks for the tip! 

Hi Bob,
I was mistaken. The article was in The Shelby American, Sept-Oct 1979, Volume 4 Nuber 5, Page 9.

I would not use synthetic grease like the redline product. Reason is the synchros will not be up to speed - the grease is too slippery and thus not competent for use. Really the OEM lubricant is best for a variety of reasons.

I am thinking of buying a 69 GT500 and was wondering if anyone can tell me anything about it such as options, original color, etc. The Vin number is 9F02R482192. Thanks in advance.

...And history was made. Think about that. With no Mustang, the car world would be very different...
