4wd to 2wd conversion question

I am looking to buy a 69-72 blazer, I want a 2wd but may end up buying a 4wd and converting to 2wd since there are more 4wd available. I just found a 2wd crossmember with gearbox, upper and lower control arms, spindles, rotors and calipers. The pic looks like it's a bolt in crossmember, is this gonna be a bolt in coversion to 2wd for the front on a 69-72 4wd blazer? If so what is this worth?

Re: 4wd to 2wd conversion question

It wont be exactly a bolt in conversion..
You have to drill/grind out a bunch of rivets on the non needed 4X4 stuff. IE: Front spring perches/radiator core support mount and modify or use a factory 2WD core support brackets, outer shock stiffeners, shackle bushing brackets etc.
Then drill 36 holes for the front crossmember, transmission crossmember, front sway bar, motor mount towers, shift linkage bracket, enlargen the front shock upper mounting holes to accept the 2WD studs.

Then you will be able to bolt the 2WD stuff in.

Livrat probably knows more about the conversion than anyone on the board having many of them.

Re: 4wd to 2wd conversion question

is this the best route to go for the conversion? I only ask because I have an opportunity to purchase the front suspension and crossmember from a 2wd 71-72 5 lug, just want to know if this would make it easier than using a setup from a 73-87 front suspension

Re: 4wd to 2wd conversion question

either one is the same amount of work to put in.. Although to make it the easiest you will need all the front brake lines, power brake booster, master cylinder, proportioning valve and motor mount towers off of a 71 /72.
Some people prefer the inner rubber bushings on the 73 and up lower control arms over the steel 71/72 style. Just a matter of choice there.
If you have the 71/72 assembly avaliable and its fairly inexpensive
($100 or so).. Personally I would go for it.

Re: 4wd to 2wd conversion question

this may not be the popular view but, im my experience its always better to just wait and buy what you want. Conversions are lots of work, and if you are like my everything under the sun WILL go wrong

i would just keep looking
