Good one Jim, Looks the business. Remember diff side has 1310 series U joint which probably does`nt match the slip yoke size on tranny, so a mix and match reqd. ie weld in tube yoke must be 1310

Thanks Ross, actually the transmission slip yoke is a 1310 size as well, because it is for a 28 spline 289 top loader. The larger yokes are for the 31 spline big blocks.

Just to keep post accurate for future racers, one can buy other size slip yokes for T10`s, TopLoaders, etc. Below is a link.

Blas,

Thanks. I saw a similar site but was not happy with the idea of it being a 27/28 spline shaft with a dead spot. It might be fine, but just worried me a little. Wanted something that was made specifically for a 28 spline.

No pictures today, will have some later tomorrow or Monday. Spent yesterday and today installing the MSD system, leveling the transmission tail with the differential and planning out the transmission support. The car comes with a transmission support that is set up for a Tremec and the support is about 3 inches aft of the transmission support on the tail housing for the Toploader. I have to make a bracket that will bolt to the existing transmission support and then drop down an inch and go forward 3 inches to allow it to be bolted to the poly transmission support bracket on the Toploader.

Also have been planning out the install for the race harness, wired in the kill switch and will be working on the fire system as well. Things are coming together, but there is no way that I will be ready for the July Sprints at Watkins Glen next Friday, so I will be running the MGB there to get some more track time and will have the car ready to race at the US Vintage Grand Prix at Watkins Glen September 7.
