Lt77 gearbox position

Hi guys

Can I ask the position of the lt77 when looking from underneath?

I have fabbed the existing mountings and cross member and when looking underneath the gearbox is isnít exactly level with the floor of the car. I would say it hangs about 1Ē below the floor at the prop shaftt end

My question is should the gearbox be level with the floor?

Thanks

Generally speaking....no!
Engine/xsmn usually has a power angle of, typically, 3 degrees tail down....matching the rear axle pinion of 3 degrees up.

Yep sussed it. I was 15mm out on the new towers on the cross member . so rather than re fan again I got some new cotton reels 15mm thicker and these worked spot on. Now it sits neatly and the gear shift protrudes vertically into the car.

Thanks for input
