The Marks adapter...I don't use it as they intended. I move the t-case crossmember back to get the engine as far back as possible, about an inch and a half from the firewall. Using it as they designed leaves you with a very short front driveshaft, and on lifted trucks, every inch you can add to the front driveshaft will be beneficial.
Thanks.

I got this VSS module from Jags that Run recently but they got the mating flange hole layout wrong. They made it with evenly spaced hole layout but the holes are not regularly spaced. I had a local shop remake the mating flange with the correct layout. Also they provided a reluctor with 40 teeth. I am told it is programmable so that it should work. I hoping they are right.Getting the proper VSS to communicate with the manual trans ECU was trickier than I thought. I called APT instruments and they had a solution, but it was too complex. Of course there's always Dakota Digital, but gadgets don't really do it for me. But I found a really cool solution. Just down the road from me...ok, 125 miles... is a shop called Jags That Run. They are famous for V8 swaps in mid year Jaguars. They just happened to have exactly what we needed, with no doohickeys, just a simple reluctor ring and an OE GM VSS. Part of the issue lay with the pulse requirements of the manual trans computer; 17 pulse, but they had the right parts in stock.
It's a really neat solution. Check it out.
I had a couple leaks to fix in the t-case while I was in there, but other than that, installation was very easy.
But of course, there is another problem. The new VSS is clocked so that it interferes with the speedo correction gearbox. Out of the frying pan, into the fire...
I'll have to have a new gearbox made in 90 degrees. APT can help me with that.
