i found a decent rust free 79 bronco with a 351/400 4spd 205 and same paint as the patriot project (sky blue with white pinstripes) for $750 it wont be at my house for awhile because i have to move another truck to a friends property first but was wondering if a np435 will be a direct swap for a t18 if thats what it has now and what gear ratio the t18 granny is. also if the the drievshafts would be the same for both of them. thanks
