Problems with lowering blocks?

My problem is that the belltech drop blocks I received for my 95 p/u (not tacoma) dont seeem to want to fit.The locator pin on the leaf spring pack is way too big for the blocks to fit on top of them. Also that means that the hole in the axle housing is too big for the locator pins built into the blocks.Did any of you run into similar problems and what did you do to solve them?

thanks in adnvance

on my isuzu and my friends i had to file down the centering pin on the drop block to fit. had no problems with them with the 2 years they were on my truck. i doubt thats the best way to do it, but it works.

I didn't have a problem with the spring bolt fitting in the bottom of the block. As for the top hole being to big, mine had a rubber isulator or something from the factory that looks like a peice of c-channel. The top pin of the block will fit right in it if your truck came equipped with it.
