Topic: v6 crawl box install and v6 twin stick install questions

[JOE 88]

i just received my twin sticks and crawl box assemblies for my 88 v6 pickup. and i am having some troubles. i found that the addapter plate that mounts the crawl box to my t-case has clearance problems. my t-case has a cover around the input shaft. that makes contact with the addapter plate. i think all i need to do make a small notch in the addapter plate. but i am wondering if anyone else has had this problem?

My second issue is that i don't know if there is anything that i need to do to my v6 t-case in order to install my twin sticks. or dose it just drop right in. im kind of disapointed that i did not get any instructions on either of these products from marlin crawler .  if anyone has any input it would be appreciated very much thanks

The instructions are on the tech page but to get there you have to click on the store button.

i read what was on the tech page. and is says nothing about clearance problems for my t-case. and the instructions for twin stick are for 4cyl not v6 chain drive t-case.

Not sure what's up with the clearance issue but anytime you install twin stick you have to remove the shift/guide rail so you can remove the center detent ball. Search around you should be able to find pics of this.

Few questions for you.

If I read this right you are putting a gear drive T-case in front of your chain drive t-case?

Did you make sure the coupler is all the way in on the tranny? They are real tight and really have to be hit pretty hard. I used a block of wood and a 4 pound hammer.

Is the seal adapter seated all the way in on the adapter plate?

Did you do the grinding on the tranny as per instructions?
