[Ski-me]

Late to the game but love the project!

I do have the 90/91 NP241 in my Blazer and had no issues with 35" tires. Plenty stout.

If you do consider a SYE, I ended up going with JB Conversions....great company but really hard to get kit if they are out of stock!! Like several and several months! However, Tom Woods makes a kit too, but I prefer JB's because it's an all new shaft. Woods ends up chopping off an old, used one and making that work. Front Range showed a cheaper slip yoke CV driveshaft, but Woods said I may have vibration issues due to the larger mass of the CV joint on the slip. Therefore I bit the bullet and did the full SYE setup.

Also, I opted for Tom Woods driveshaft but had to get it re-balanced upon arrival. Local shop did say that he's seen a lot of Woods/aftermarket driveshafts requiring balancing upon arrival.

I went with the 90/91 because of the VSS and used it for the electric speedo. Otherwise, my speedo kept bouncing around due to cable driven.

I just gave Larry a skid plate but he came and met me in person....hopefully someday I'll be able to go to his shop and see his 8.1L conversion (s)! Pretty cool and factory looking!
