it seems as i have noticed on several these 250 highboys that the rear driveshaft's telescopic area is very EXTREMELY close together....ive hit bumps in the road...wait reflectors and heard the driveshaft telescopic area bottom out into e/o....i dont want to know what will happen if i hit a serious bump in the road(driveshaft punching through t-case maybe?) what can i do? blocks? springs? it has four inch blocks already....came stock...oh and whats your height between the fender and the tire in the front?(if anybody has a 77 highboy with 33s...)

 

Do you mean the slip yoke? Maybe you don't have the original shaft in it anymore. Over the years someone could have swapped it out. I don't think it would come that close from the factory. Do you know of anyone else with a truck like yours to compare with?

 

no i dont but i have seen them in the junkyard with a similar problem....but yesterday i went and yanked the stock 4 inch block and threw in sixes....and put drop shackles in the front to even it out....will drop shackles in the front damage ne thing?

 

oh and i found that chevy that has those drop shackle brackets(well one of them) it was a 55 through like 62 or sumthin like that...
